The ESA atmospheric Validation Data Centreis the official ESA repository for validation and campaign datasets

EVDC serves the needs of both datasubmitters (e.g. Cal/Val campaign teams)
and data users (i.e. both Cal/Val campaign
teams and international science community).
EarthCARE Cal/Val is considered
for 'campaign use’,
which implies that data will only be circulated
within the EarthCARE Cal/Val Team (ECVT).

GEOMS Tool and Data Formatting Templates
Data hosted in EVDC
or linked from primaryarchieve; support for GEOMS
data formatting and upload

The GEOMS Tool is a set of functionalities to support data submitters with the data upload to EVDC, hereunder- Create GEOMS compliant files from a set of ascii metadata and data- Create new metadata templates for their specific measurement principles
The tool automatically generates the GEOMS headers and files and makes them available for upload anddownload in EVDC.

GEOMS Tool and Data Formatting Templates

Selected datasets
converted to GEOMS:
53% of PIs find areporting templateà Create newtemplates

Data reporting templates are used as an additional guidance to

50% of datasets notstored in a primaryarchive

file formatting for specific instrument types.
This can be useful to make sure all measurements from similar
instruments, e.g. a LIDAR, within a monitoring network report
the same mandatory data variables.

ECMWF service
https://evdc.esa.int/ecmwf/
Through collaboration with the ECMWF, EVDC is providing access to daily updated analyses and forecast
data files of global gridded meteorological parameters, such as temperature, geopotential height, zonal windand meridional wind. Analysis and forecast up to 240 hours for levels are updated on a daily basis. Data forboth the Northern hemisphere and the Southern hemisphere are available.
