The number of the first measuring period  shall be used to indicate the period for analysis (e.g. when the samples from period 9, 10, 11 and  12 are combined into a single sample for the analysis, this sample will be given the period number  9). Information with regard to meteorologic monitoring (41)  Site code In and near the plot a number of sites can be identified. As meteorologic instruments can be  installed at different sites, each site has to be identified. The exact details of the site are to  be included in an annex to the document with the meteorologic evaluation. Examples of possible site  codes are: In the plot 1:  under canopy at standard meteorologic height (1,50 m) 2:  under canopy at height of 2 m (2,00 m) 3:  under canpoy at ground level (0,10 m) 4:  at canopy height 5:  above the canopy 6:  under canopy at depth of 20 cm ( P0,20 m) Outside the plot 7:  open field, at standard meteorologic height (1,50 m) 8:  open field, at ground level (0,10 m) 9:  open field, at height of 10,00 m .  .  . etc. (42)  Instrument code The following codes shall be used for the samplers for meteorology: 10:  manual reading 20:  mechanical recording 30:  paper recording 40:  digital recording (stand alone) 50:  digital recording (integrated datalogger) When more instruments of different types, brands, ect. are used, the single numbers can be used  (e.g. 11; hair hygrometer, 12 wet/dry bulb).

(50)  Observed damage The number and name under which the damage is mentioned in the Form 8d (if applicable) or a short  indication and a reference to a more extensive explanation in the survey or evaluation report (see  Annex IX, paragraph II.8) shall be stated. The same report should also include details on  extremity, symptoms and spreading of the damage.`  ANNEX II To Regulation (EC) No 1091/94 the following Annex VIII is added: 'ANNEX VIII COMMON METHODS FOR DEPOSITION MEASUREMENTS ON THE PERMANENT OBSERVATION PLOTS I. Generals remarks The measurements are to be carried out on a selection of the permanent observation plots in a  continous way. At least 10  % of the permanent observation plot shall be selected for the  monitoring of deposition by the Member States. Measurements on throughfall (under canopy), stem  flow (under canopy, in beech) and wet-only or bulk deposition (in an open area in the forest) will  be mandatory. The installation of the equipment for the mandatory items shall be completed by  December 1995. All other measurements such as: stemflow (in other species than beech), fog and  air-concentrations are optional. The depositions monitoring will be done on a fixed period basis (for example monthly or weekly). To  reduce analysis costs samples may be combined from a number of consecutive periods. The following technical details are based on the results of the Expert Panel on Deposition of ICP  Forests. Reference is made to the manual prepared by this Expert Panel especially regarding  specific details of sampling equipment, sampling techniques, quality assurance and data handling. II. Monitoring methodology II.1. Monitoring under the forest canopy Whenever possible the measuring equipment for throughfall shall be installed in the actual plot. To  avoid damage to root systems, the parts that have to be installed in pits (collectors, recorders,  etc.) could be installed outside the actual plot in the bufferzone. In beech forest equipment shall  also be installed for the collection of stemflow. As these collectors should also be stored in a  (or the same) pit, it is recommended to select trees outside the actual plot, in for example the  bufferzone. The measurements of throughfall and stemflow should be made in such a way that the results are  representative for the plot area. This means that a sufficient number of samples should be used. II.2. Monitoring in an open area in the forest At a location near the actual plot (within a distance of 2 km), wet-only and/or bulk deposition  collectors shall be installed. The location should be selected in such a way that the surrounding  objects are not closer than two times their height. II.3. Measurement period The measuring will be made monthly, weekly or at a time interval between the two, e.  g. every two  or three weeks, depending mainly on the general weather conditions at the specific plot  (evaporation and growth of algae in the sample containers should be avoided). When it is necessary to use different measuring periods during the year (e.  g. weekly in summer  and monthly in winter), two separate monitoring periods shall be identified and the results shall  be reported separately on the forms. Within one monitoring period the lenght of the measuring  period shall be constant. The same measuring period shall be used for the monitoring under the  forest canopy and the open area monitoring. II.4. Sampling, sample handling Clean collection gauges and containers are to be used for the collection of samples. Deionized  water shall be used to rinse the equipment. It is important that the containers are kept away from  light and kept cool during the sampling and transport. In sunny and warm conditions preservatives  may be added to prevent the growth of algae. In this case only such preservatives should be used  that do not interfere with the analysis of any ion of interest. II.5. Pretreatment of samples, transport and storage The volume of each collected sample form each individual throughfall, stemflow or open air  collector shall be determined. The samples may be analyzed separately or mixed with samples from  parallelly installed equipment of the same type. Throughfall, stemflow or open air samples shall be  analyzed separately. Samples from stemflow measurements can only be pooled for trees of the same  species and similar size and dominance. Samples from short periods may be analyzed as they are, or can be mixed to monthly samples before  analysis. If samples are mixed they should be mixed in proportion to the total sample volume. The samples shall be transported to the laboratory as soon as possible (preferably in cold boxes)  and kept in a cold (4  °C) and dark store until analyzed. II.6. General background information The following information shall be collected: -  plot number, -  sampler code, -  first date of monitoring period, -  last date of monitoring period, -  number of (equal) measuring periods in monitoring period. Additional optional information can be collected, which is useful for the interpretation of the  results, such as canopy roughness, leaf area index etc. II.7. Chemical Analysis In each sample the following parameters shall be determined mandatory (Man) or optional (Opt.): >TABLE> II.8. Data transfer The Member States shall forward this information in a standardized form to the Commission for each  plot where deposition has been monitored (see Annex VII, Forms 7a, 7b, 7c and 7d).`  ANNEX III To Regulation (EC) No 1091/94 the following Annex IX is added: 'ANNEX IX COMMON METHODS FOR MEASUREMENTS OF METEOROLOGY ON THE PERMANENT OBSERVATION PLOTS I. General remarks In the period to mid 1996 a test period is foreseen during which, on a voluntary basis, in a  limited number of permanent plots (10  %) meteorologic measurements are carried out. In the second  half of 1996 an evaluation will take place and the details and intensity of the continuation of the  meteorologic measurements will be decided upon. Besides the observations on a limited number of  plots, the recording of observed damage caused by meteorologic phenomena should be executed on all  permanent observation plots. The meteorologic observations are divided in three parts: A.  execution of measurements of actual meteorologic situation on or close to the plot (limited  number of plots) B.  determination of long-term climatic situation (all plots) and potential damaging  events/phenomena (limited number of plots) C.  observation of damage of trees in the plot caused by extreme weather situations (all plots) The actual measurements (A) will be carried out on a selection of plots, preferably plots which are  also used for the monitoring of deposition (See Annex VIII). The Member States are free in the  selection of methods, equipment and frequency of the measurements during the test period. It is  foreseen that in the evaluation process recommendations for methods, equipment and frequency are  formulated. II. Inventory methodology II.1. Location of sampling equipment The measuring equipment for all monitoring of the meteorologic parameters (A) will be located in or  close to the plot. Certain parameters (rainfall, wind, radiation, etc.) have to be measured in an  open area in the forest. Other parameters (e.g. soil temperature) may be better monitored under  crown cover. In the test period no restrictions nor explicit installation procedures are given.  When parameters such as solar radiation, rainfall, etc. are monitored, a sufficiently large "open  area in the forest" outside the stand should be selected. This location should be as near as  possible, be in similar situation (slope, elevation, etc.) and preferably within a distance of 2 km  of the plot. Whenever possible a combination with the equipment for deposition should be made. To avoid  disturbances to the roots and soil situation, the equipment should be placed in such a way that the  equipment can be reached and maintained without actually passing through the plot. II.2. Methods to measure the actual meteorologic situation in or close to the plot (A) For the test period the Member States are free in the selection of methods, equipment and measuring  frequency. On a limited number of plots the meteorologic situation should be monitored. -  If possible an intensive continuous meteorologic measuring station should be installed in the  limited number of plots. The following parameters are then recommended to be measured in a  continuous way: >TABLE> In places where snow is common special snowcollectors should be installed. -  As an alternative for situations where no such intensive continuous meteorologic stations can be  installed it is recommended to install, on the limited number of plots, equipment to monitor the  following parameters with the frequency: >TABLE> In some cases wind and solar radiation information can be obtained from nearby meteo-stations. II.3. Collection, storage and submission of information The following information shall be collected: -  plot number, -  exact details of the used equipment, -  location of the plots (longitude, latitude, altitude) and of equipment (relative to the plot), -  start and end dates of the measurements, -  frequency (number of periods). The data of the detailed measurements (temperatures, rainfall, wind etc.) should not be reported to  the Commission, but kept in safe storage by the Member States. For each plot where the measurements  have been executed a summary of the collected measurements shall be compiled and submitted to the  Commission by mid 1996. This summary will contain information on a monthly or four-weekly basis,  using the forms XX1993.PLM (8a) and XX1993.MEM (8b). II.4. Determination of long-term climatic situation (B) For each plot the long term climatic situation shall be determined as good as possible. As no  actual plot data is available, existing data shall be used to estimate the long-term (open area in  the forest) climatic situation of the plot. This will be done only once. The results are presented  to the Commission using form XX1995.MEC (8c). II.5. Determination of potential damaging events and phenomena (B) For each plot where meteorologic measurements are taken a start shall be made with the preparation  of a list of potential damaging events and phenomena. Each event or phenomenon shall be defined in  meteorologic terms, using the parameters available for the plot. This list of potential damaging  events and phenomena will be continuously updated by the Member States, each time when more  information becomes available. The information on events and phenomena shall be reported to the  Commission using form XX1995.MEL (8d). II.6. Reporting of pre-defined events and phenomena and its occurrences/extremity (A and B) For the limited number of plots where detailed information has become available the occurrence and  extremity of the pre-defined events/phenomena (II.5) will be determined. Of each listed  event/phenomenon the number of occurrences and the relative extremity shall be indicated. The  occurrences and extremities shall be submitted to the Commission using form XX1995.MEO (8e). In  case events/phenomena have been added or changed, the occurrences and extremities of the past years  will be updated as well. II.7. Reporting of actually observed damage (C) Whenever during the visits on the plot damage has been observed that has a clear meteorologic  cause, this shall be reported to the Commission by mid 1996 using form XX1995.MED (8f). The reporting will include the cause (drought, storm, frost, hail, etc.) the observed damage  (foliage loss, breakage or dying of branches or new shoots, etc.) and an estimate of the period in  which the event took place. II.8. Evaluation report on meteorology The Member States shall forward to the Commission together with the information in the standardized  forms (in digital format) as described in paragraphs II.3, II.4, II.6 and II.7 an evaluation report  with the background information on the used methods, models and interpretations of results. For the reporting of the list of the pre-defined events/phenomena (II.5) it is recommended to use a  form similar to the example form 8d. These forms could be attached as an annex to the meteorologic  evaluation report.`
