OLCI Level-1 Earth Observation Processing
OLCI Level-1 Earth observation processing mainly involves calibrating the numerical counts contained in Instrument Source Packets (ISPs) into radiances, geo-locating acquired pixels on the Earth's surface and re-sampling the image onto an orthogonal product grid representing the instrument ideal swath. In addition, quality flags, meteorological annotations and pixel classification flags are computed and appended to the output Level-1B products.
This processing involves the following steps:
Note: Since no Level-1A product is generated, the entire Earth observation processing is considered to be Level-1B (no specific Level-1A processing step is defined).
