Processing Baseline 2.33 - April 2018

Processing Baseline 2.33 was introduced to accommodate the following changes and evolutions:

SRAL Level 1:

• When the instrument enters acquisition mode during the period covered by a product, a new netCDF file will be available within the L1B product folder. The netCDF file name is acquisition.nc.
• Information about the ascending node time and longitude is more accurately recorded in the manifest files.
• Run time anomalies have been fixed.

SRAL Level 2:

• Correction of a 5 mm bias between the modelled dry tropospheric correction at zero-altitude (mod_dry_tropo_zero_altitude_01) and modelled dry tropospheric correction at the measurement altitude (mod_dry_tropo_meas_altitude_01).
• Several fixes for LRM mode, important during Sentinel-3B commissioning; SAR mode data is not affected by these fixes.
• As with L1, information about the ascending node time and longitude will be more accurately recorded in the manifest files.
• C Band Corrected Longitude (lon_cor_20_ku) and C Band Corrected Latitude (lat_cor_20_ku) now are now defined everywhere as being in Ku Band. They are computed over Greenland and Antarctica surfaces and filled with the uncorrected latitude over other surfaces.
• Run time anomalies have been fixed.
