Level-3 Cryosat-2 [2011, 2019] along-track 5Hz product, sea level anomaly, ~1km resolution.

Along-track Sea Sevel Anomaly (SLA) and derivate/complementary variables. The processing use upstream L2 products with 20Hz sampling and includes : # a multi-mission cross-calibration processing aiming to reduce global and regional biases observed between measurement from different altimeter missions # a low-pass filtering aiming to remove short wavelength signal dominated by residual measurement noises. # a sub-sampling to reach the 5Hz final sampling
