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_L2_NN
<VENDOR_ID>_<INSTRUMENT_ID>_<PRODUCT_LEVEL>_<ALGORITHM>
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_NN_yyyymmdd_nnn_i_vv.nc
- yyyymmdd- year, month and day
- nnn - orbit number
- i - orbit node: A or D
- vv - version (v1, v2...)
