Analysis of minimum number sampling points - Spain 

1. Executive Summary 

The aim is to identify gaps in the monitoring network for Spain according to the 
revised Ambient Air Quality Directive (Directive (EU) 2024/2881). 

The analysis is conducted considering the data officially reported by Spain for the 
last five years (2019–2023) to EEA’s Repornet2. Data has been extracted from 
different tables available at EEA AQ portal (Data tables – European Air Quality 
Portal). 

The analysis focuses on the situation in the year 2023, based on the most recent 
validated data available. 

The analysis provided includes three key elements: 

•  Analysis of the minimum requirements per air quality zone. 

•  Analysis of requirement of urban/suburban background sampling point at 

NUTS-1. 

•  Analysis of monitoring critical levels in all air quality zones. 

Analysis of the minimum requirements per air quality zone 

Firstly,  the  minimum  requirements  of  the  fixed  monitoring  sampling  points  in 
current air quality zones for all pollutants was checked. This has been evaluated 
against the new minimum number of sampling points as per Annex III, Point A, 
Section 1 of the revised Ambient  Air Quality Directive. This evaluation covered 
both  the  minimum  numbers  required  in  Tables  1  and  2,  as  well  as  the 
requirements for the minimum number of background/hotspot sampling points as 
indicated in the text beneath the tables in the cited section and the ratio between 
background/hotspots,  applied  to  the  minimum  required  number  of  sampling 
points. Moreover, for ozone, the % of suburban sampling points was evaluated. 

This analysis has been conducted exclusively based on Tables 1 and 2 of Annex 
III, Point A, Section 1. Consequently, the possibility of a 50% reduction specified 
in Tables 3 and 4 has not been considered. This limitation is acknowledged. 

The table below shows the obtained results, along with a brief legend to clarify 
the data:

Analysis of requirement of urban/suburban background sampling point at 
NUTS-1 level. 

The  second  analysis  checks  whether  there  is  at  least  one  urban  background 
sampling  point  for  PM2.5  and  NO2  at  the  NUTS-1  level.  Moreover, it  evaluates 
whether there is at least one sampling point per million inhabitants for PM2.5 and 
NO2, calculated for urban areas with more than 100.000 inhabitants. 

The calculation is based on municipalities, using EUROSTAT data1 

In Spain, all NUTS-1 regions have at least one urban background sampling point 
for both NO2 and PM2.5. 

For  NO2,  the  requirement  of  having  at  least  one  sampling  point  per  million 
inhabitants, calculated over urban areas with populations exceeding 100.000, is 
met. 

For  PM2.5,  the  requirement  of  having  at  least  one  sampling  point  per  million 
inhabitants, calculated over urban areas with populations exceeding 100.000, is 
met. 

Analysis of monitoring critical levels in all air quality zones. 

The  third  analysis  is  to  check  whether  the  current  sampling  points  monitoring 
critical levels in all air quality zones in Spain are sufficient in number to comply 
with the requirements. 

In Spain, maximum SO2 concentrations exceed in some zones the assessment 
threshold or the critical level. The following table shows this situation.

Analysis of minimum number sampling points - Spain 

2. Introduction 

This report presents the current state of air quality networks in Spain, with the 
objective  of  assessing  compliance  with  the  minimum  requirements  set  by  the 
revised Ambient Air Quality Directive (Directive (EU) 2024/2881). The purpose of 
this evaluation is to identify any gaps that Spain would need to address to meet 
the monitoring requirements laid down under the revised Directive. 

The analysis focuses on the situation in the year 2023, based on the most recent 
validated data available. 

3. Assessment  of  the  compliance  with  the  minimum 

number of SPOs in air quality zones 

The  objective  of  this  first  step  is  to  check  the  number  of  monitoring  sampling 
points in current air quality zones for all pollutants in Spain and evaluate them 
against the new minimum number of sampling points as per Annex III, Point A, 
point 1 of the revised AAQD – both in relation to the minimum numbers prescribed 
in Tables 1 to 2, as well as in relation to the requirements on minimum number of 
background sampling points (text beneath the tables in the cited point 1). This 
assessment is based on the situation in 2023. 

It should be noted that any changes to the network for the year 2024 and 2025 
have not been considered in the report. 

The situation of each zone over the past five years is assessed to determine its 
status with respect to the assessment threshold (as set out in Annex II, Section 
1 to the revised AAQD ). This has been done primarily using statistics calculated 
by EEA based on primary validated data (E1a). 

It is important to note that there may be zones for which evaluations cannot be 
conducted for certain pollutants across any of the five years due to lack of data. 
In this situation an attempt has been made to extract results from data flow G. 
Despite this, for SO2 and CO, the reporting metric provided may sometimes be 
unusable as it differs from the Assessment Thresholds values established by the 
revised Directive. 

Annex 1 shows the status of each zone in terms of whether it has been evaluated 
against the assessment threshold. 

• 

In Spain, there are 19 zones where it has not been possible to conduct an 
assessment against the threshold for at least one pollutant.

Analysis of minimum number sampling points - Spain 

After determining the status of each zone concerning the assessment threshold, 
the  minimum  number  of  sampling  points  required  by  the  revised  Directive  is 
calculated based on the population of each zone, as outlined in Tables 1 and 2 
of Annex III, Point A, point 1. 

This analysis has been conducted exclusively based on Tables 1 and 2 of Annex 
III, Point A, Section 1. Consequently, the possibility of a 50% reduction specified 
in Tables 3 and 4 has not been considered. This limitation is acknowledged. 

Subsequently, this minimum number must be compared with the actual number 
of sampling points for fixed measurements present in the zone. To identify these 
sampling points, all SPOs submitted as Fixed Random Measurements for at least 
one  of  the  five  years  analysed,  along  with  those  categorized  as  Fixed 
Measurements that meet the data coverage requirements established in Annex 
V,  Point  B,  have  been  considered.  Additionally,  these  sampling  points  must 
currently be operational. 

These  are  the  conditions  that  a  Sampling  Point  (SPO)  must  meet  to  be 
considered in the analysis: 

• 

• 

• 

It must be characterised as Fixed Random or Fixed Measurements for 
at least one of the five years analysed. 

It must be operational in 2023. 

It must have been reported for the purpose of air quality assessment of the 
zone, using the appropriate metric, in dataflow C (Assessment Regime). 

The  following  table  presents  the  analysis  conducted  for  all  zones,  where  the 
following situations may occur: 

•  Below  the  assessment  threshold:  a  minimum  number  of  points  is  not 

required (<AT). 

• 

• 

• 

The number of SPOs in the zone exceeds the minimum required by the 
Directive. 

The number of SPOs in the zone does not meet the minimum required by 
the Directive. 

The  zone  cannot  be  evaluated  concerning  the  assessment  threshold 
(NEV). 

• 

The zone does not measure this pollutant.

Interpretation of the minimum sampling points analysis (see Table 2) 

Spain has 125 out of 485 (i.e. 26%) sets of zones and pollutants, in 2023, where 
the minimum number of SPOs required in Tables 1 and 2 of Annex III, Point A 
is not met.

Additionally,  even  if  a  zone  meets  the  minimum  number  of  sampling  points 
established  in  Tables  1  to  2,  the  Directive  prescribes  additional  requirements,

3.1. 

Specific assessment of suburban areas for Ozone 

In  the  case  of  ozone,  in  agglomerations,  at  least  50  %  of  the  sampling  points 
shall be located in suburban areas. 

The  table  below  presents  the  list  of  zones  (that  meet  the  minimum  number  of 
Sampling Points (SPOs) criteria established in Table 2 of Annex III, Point A) but 
do not  comply  with this requirement of  50%.  Specifically,  these  are  the  zones 
that lack at least 50% of their SPOs located in suburban areas (noting that this 
50% refers to the minimum number of points required by the Directive, rather than 
the total number). 

Spain has 17 out of 47 agglomerations for O3, where the following requirement 
is not met: at least 50% of the SPOs are located in suburban areas.

sampling point at an air pollution hotspot, in accordance with Point B of Annex 
IV,  provided  this  does  not  increase  the  total  number  of  sampling  points.  For 
nitrogen dioxide, particulate matter, benzene, and carbon monoxide, there 
must  be  at  least  one  sampling  point  focused  on  measuring  contributions 
from transport emissions. However, in cases where only one sampling point 
is required, this should be situated at an air pollution hotspot. 

For the purposes of the analysis, the following considerations have been made: 

•  A  hotspot  for  nitrogen  dioxide,  particulate  matter,  benzene,  and  carbon 

monoxide is considered to be any traffic sampling Point. 

•  Only  those  zones  that  already  meet  the  minimum  sampling  point 
requirements  established  in  Tables  1  and  2  of  Annex  III,  Point  A  of  the 
Directive have been evaluated 

• 

For  benzo(a)pyrene,  ozone,  metals,  and  SO2,  no  assumption  has  been 
made and therefore  the definition of a hotspot is left to the discretion of 
each country. 

The tables in 3.2.2 and 3.2.3, therefore, present the status of each zone in respect 
of that requirement.

3.3. 

Specific Assessment factor urban background and 

hotspot. 

For each zone, for nitrogen dioxide, particulate matter, benzene and carbon 
monoxide, the total number of urban background location sampling points and 
the  total number of  sampling  points  required  at  air pollution  hotspots  shall  not 
differ by more than a factor of 2, applied to the minimum required number of 
sampling points. In this case, a hotspot is assumed to be a traffic sampling point 
(SPO). 

The  zones  used  for  this  analysis  are  those  that  were  classified  as  “Meets  the 
requirements” in the section “Specific Assessment background and hotspot,” and 
where  the  minimum  number  of  sampling  points  required  by  the  Directive  is 
greater than 1 (to ensure an adequate calculation of the ratio).  

For the purpose of this analysis, suburban background stations have also been 
considered as urban background. With regard to traffic sampling points, all SPOs 
classified as "traffic" have been included, regardless of their area classification 
(i.e. whether they are located in urban, suburban, or rural areas). This approach 
applies  to  the  minimum  required  number  of  sampling  points,  not  the  actual 
number installed, in line with the proportionality requirement between background 
and hotspot sampling locations.

4. Assessment  of  the  compliance  with  the  minimum 
number of SPOs Average Exposure Reduction 

This  section  analyses  the  situation  of  each  country  concerning  the  minimum 
number of sampling points for fixed measurements to assess compliance with the 
PM2.5  and  NO2  average  exposure  reduction  obligations  for  the  protection  of 
human health (Annex III, Point B). 

4.1. 

Analysis  urban  background  sampling  point  at 

NUTS-1 level 

The  first  part  of  this assessment  focuses on  verifying  whether there  is at  least 
one urban background sampling point for PM2.5 and NO2 in each NUTS-1 level 
across all Member States. 

The sampling points used in this analysis meet the following criteria: 

•  SPOs categorized as fixed random measurements. 

•  SPOs categorized as fixed measurements that meet the data coverage 
requirements established in Annex V, Point B of the new directive. 

•  Currently operational SPOs. 

•  SPOs belonging to urban background or suburban background stations. 

The following maps illustrate the distribution of the SPOs in each NUTS-1 level. 

Figure 1: Distribution of the SPOs in each NUTS-1 level for NO2 

As  can  be  seen  on  the  map,  all  NUTS-1  regions  have  at  least  one  urban 
background sampling point for NO2. 

46 

 
Analysis of minimum number sampling points - Spain 

Figure 2: Distribution of the SPOs in each NUTS-1 level for PM2.5 

As  can  be  seen  on  the  map,  all  NUTS-1  regions  have  at  least  one  urban 
background sampling point for PM2.5. 

4.2. 

Analysis  urban  background  sampling  point  per 

million inhabitants (over urban areas) 

This second part focuses on whether there is at least one sampling point in each 
NUTS-1  level per million  inhabitants  for PM2.5  and  NO₂,  calculated  over urban 
areas with populations exceeding 100.000 inhabitants. 

The  total  population  of  each  urban  area  exceeding  100.000  inhabitants  is 
calculated, and an analysis is conducted to determine if the Member State meets 
the criterion of having at least one sampling point per million inhabitants extra in 
each  NUTS-1  for  PM2.5  and  NO2  (using  the  same  sampling  points  as  in  the 
previous section). 

The  following  tables  show  the  number  of  SPOs  for  PM2.5  and  NO2  currently 
existing in each NUTS-1 (which meet the previously described criteria), compared 
to  the  minimum  number  of  SPOs  required  based  on  the  total  population  of  all 
urban areas with populations exceeding 100.000, including the requirement of at 
least one SPO per NUTS-1

5. Assessment  of  the  compliance  with  the  minimum 

number of SPOs monitoring critical levels 

The  objective  of  this  section  is  to  assess  whether  compliance  with  the 
requirements specified in Annex III, Point C.1. of the Directive, which establishes 
the  minimum  number  of  sampling  points  for  fixed  measurements  to  assess 
compliance with critical levels for SO2 and NOx. 

5.1.  Critical levels for SO2 

In Spain, maximum SO2 concentrations exceed in some zones the assessment 
threshold or the critical level. The following table shows this situation.
