Abstract:
CryoSat was launched on the 8th of April 2010 and is the first European ice mission dedicated to the monitoring of precise changes in the thickness of polar ice sheets and floating sea ice.
CryoSat is the first altimetry mission operating in SAR mode and continuous improvements in the L1 Instrument Processing Facility (IPF1) are being identified, tested and validated in order to improve the quality of the L1B products. Current IPF, Baseline C, was released in operation in April 2015 and the second CryoSat reprocessing campaign was jointly initiated, proving the users, within a few months, with a coherent data set from July 2010 until present time.
Right after baseline C release, ESA have been collecting inputs for the next processor version, baseline D, planned to be operational in mid 2018. This poster will detail the evolutions that are currently planned for the BaselineD SAR/SARin L1B products together with the expected quality improvements. The major change in Baseline D will be the migration into netCDF format, which is now the standard for altimetry missions. Another change involves the accuracy of the Attitude information, which will be increased by correcting for the aberration of light, thus improving the interferometer performance. Then, the stack characterization parameters will be extended including for example the Stack-Peakiness, which, computed before the multilooking, gives an indication of the peakiness of the stack. The full list of planned changes will be provided in this poster.
