US government shutdown effects on CryoSat geophysical corrections and parameters

23 January 2019

The CryoSat users are informed that the US government shutdown currently on-going is affecting the services that are responsible for providing NOAA's input data products used in CryoSat ice and ocean processing chains.

The CryoSat L1b and L2 products with dates of validity starting on 21 December 2018 are therefore affected by this situation. As a consequence, the quality of CryoSat related geophysical corrections and derived parameters (e.g. sea ice concentration in ice products and GPD+ wet tropospheric correction in GOP) are potentially degraded.

Users will be informed at a later stage to what extent L1b/L2 parameters are directly or indirectly impacted and once the US services return to normal.
