All PIs are asked to establish contact with the ESA Data Centre: nadirteam@nilu.no / databasemanager amf@nilu.no

Data agreement protocol must be signed. Access to database discs, preliminary Cal/Val data from the ECVT, and EVDC tools in only granted to those who have signed the data protocol.

ECVT members are requested to read, sign the EarthCARE data protocol, and make use of this correlative data repository by sharing their data (upload) and working with others' data (download).

In order to avoid unnecessary misunderstanding/misinterpretations when working with different sets of data, ECVT members are expected to standardise the metadata of their measurements according to GEOMS (Generic Earth Observations Metadata Standard). To support the standardization, there are GEOMS tools and templates available and when these are not sufficient, PIs/co-Is can ask from support from the EVDC team.

Each Cal/Val team or data network that plan to share and exchange their data within ECVT should take the opportunity and use the rehearsal period to upload at least one demo dataset to EVDC. One test dataset for each instrument type for each station should be uploaded to EVDC as soon as possible for readiness tests. For the rehearsal period, this file does not necessarily need to be in GEOMS format.

Status of test files during the rehearsal is found at https://ecvt.csde.esa.int/confluence/display/ECAOPI/EVDC+GEOMS+METADATA

Data upload via web API:

Visit https://evdc.esa.int/upload/ --> select file from you local machine and press "submit file" button. Only GEOMS formatted data files are supported in the web API.

Data upload via blind-drop:

From a terminal: Log in to machine upload.nilu.no with your evdc account using sftp and put data in the "blind-drop" folder named /viper/nadir/evdc/incoming/ (EVDC team will monitor this area and contact you after you have added files)

Data upload directly to a campaign folder:

From a terminal: Log in to machine upload.nilu.no with your evdc account using sftp and put data in the "ECVT" folder named /viper/nadir/projects/earthcare/ in a suitable folder. (EVDC team will monitor this area and contact you after you have added files. Users are allowed to create their own directories)

Data download via web pages:

Visit https://evdc.esa.int and log in to the portal (upper right corner) with your provided user name and password.

Goto "Search Cal/Val Data" https://evdc.esa.int/search/ and select from dropdown menu "Other" --> "Framwork" = EARTHCARE. (Note that the defualt date is set to the 3 last months in the "Time and Location" box).

Scroll down and select "Submit".

Data download directly from a campaign folder:

From a terminal: Log in to machine download.nilu.no with your evdc account using sftp and change (cd) to the "ECVT" folder named /viper/nadir/projects/earthcare/ Users are allowed to list and download all data in the subfolder of this area.
