In Situ TAC is the IN SITU OBSERVATIONAL COMPONENT of The Copernicus Marine Environment Monitoring Service.
In Situ TAC integrates thousand of local data from on-site sensors on board of a wide range of platforms
In Situ Production Units (PUs) are responsible for collecting & standarizing data on a defined geographical area.
All the data collected & standarized by every In Situ PU is next centralized & distributed via CMEMS FTP portalImportant! FTPs are secured. First register as CMEMS user to get the access granted.
On that FTP portal all In Situ data-products keep exactly the same:
in order to facilitate selection and processing
The data files format is an implementation of NetCDF OceanSITES format.
CMEMS list a number of tools users can use for visualization & manipulation of such files
Our contribution for spreading the word about how-to-handle netCDF format can be found in:
NRT quality controls are available hereQuality control flag scale:
|0||No QC performed||-|
|1||Good data||All real-time QC tests passed|
|2||Probably good data||-|
|3||Bad data that are potentially correctable||These data are not to be used without scientific correction|
|4||Bad data||Data have failed one or more of the tests|
|5||Value changed||Data may be recovered after transmission error|
|7||Nominal value||Data were not observed but reported.Example: an instrument target depth|
|8||Interpolated value||Missing data may be interpolated from neighbouring data in space or time|
|9||Missing value||The value is missing, is not reported, is not applicable|
In Situ data-product stracture is always the same:
Distribution Units provides 2 types of products :
Collections of data files (netCDFs) continuously updated on the Distribution Units (DUs) - Automate NRTQC
Delayed mode data that has been subject of a throughout Scientific assesment - visual QC.
Build over historical data and delivered by versions, typically once a year.
