Sentinel-3 L1 SRAL
The main applications of the Sentinel-3 SRAL altimetry mission are the investigation of ocean topography and sea ice, as well as land topography including land-ice, land and inland waters.
The input data for Level-1 processing are the Level-0 products. The main function of the Level-1 processing chain is to calculate the tracker range, the sigma-0 scaling factor and the Level-1 waveforms, applying instrumental corrections to all of them. The Level-1 processing chain outputs three types of products: Level-1A , Level-1B-s and Level-1B products.
There are three types of Level-1 products:
- Level-1A products: geo-located bursts of echoes with all calibrations applied.
- Level-1B products: geo-located and fully calibrated multi-looked High Resolution power echoes.
- Level-1B-S products: fully SAR-processed and calibrated High Resolution complex echoes arranged in stacks after slant range correction and prior to echo multi-look (multi-look processing reduces noise by averaging of adjacent pixels, and thereby reduces the standard deviation of the noise level).
On this platform the NRT (near real time), STC (short time critical) and NTC (non time critical) products are available.
