Current document describes the format of the new product. Please also refer to the short summary of the CF convention prepared from the original source CF convention.

Product design

Given:

lat, lon, time, 4 parameters: Q – water vapor, W – cloud liquid, V – wind speed, T – temperature. This is for one swath, and we have 14 ascending and 14 descending swaths per day. Time is for a scan, pixels in scan are always 196, number of scans per swath is about 2000 and this varies from swath to swath.

Product ID

SOLAB_AMSRE_?

Filename

There are several patterns for filename convention. For example, all ASCAT files use next convention:

<INSTRUMENT_ID>_<PRODUCT_TYPE>_<PROCESSING_LEVEL>_<SPACECRAFT_ID>_ _<SENSING_START>_<SENSING_END>_<PROCESSING_MODE>_<DISPOSITION_MODE>_<PROCESSING_ TIME>

Therefore, filename format of the developing SOLab product may use the next convention

SOLAB_AMSRE_L2_yyyymmdd_vv.nc

  • yyyymmdd- year, month and day
  • vv - version (v1, v2...)
