PROBA-V Collection 2 Level-2A data are Radiometrically corrected segments based on Level-1C data, projected in Plate Carrée, Top-Of-Atmosphere reflectances. The PROBA-V L2A products are available in 3 resolutions 1km, 300m and 100m.
Level-2A algorithm and data
The Level 1C data are used as input for further processing in the Level 2 processor, which consists of the following steps:
- Projection and mosaicking the SWIR strips to 1 layer
- Snow/ice detection
- Cloud and cloud shadow detection
The separate processing steps are explained in the Products User Manual.
Level-2A Quality assurance
In the Level 2A product files, the quality indicator is located in the SM (Status Map) Dataset within the QUALITY Group. The SM Dataset contains a quality state indicator per pixel, consisting of an observation indicator (clear, cloud, ice, shadow, undefined), a land/sea flag, and a radiometric quality indicator per band. Check the Products User Manual for a list of the various quality bit values and how to read them. Please note that bits 8 – 11, containing additional information on the observational coverage for each band, are only available for Level 2A data. The Status Map information can be easily read in most programming languages.
A Quality Webpage is available and provides information on the Quality Assessment and the various methods applied to maintain PROBA-V’s data quality at the highest possible level, from the raw satellite observations through the value-added products available at the PROBA-V Data Portal.
