Cryo-TEMPO Baseline-B products for Sea Ice were released in January 2023. See the product downloads page for access details.
The following evolutions have been applied in Baseline-B as compared to Baseline-A (released Jan 2022). Further details are provided in the Cryo-TEMPO Product Handbook and ATBD documents.
A new region_code parameter has been included. This provided the Arctic region indentifier (0..18) for every measurement. The regions are adapted from 'A new regional mask for Arctic sea ice trends and climatologies (J. Scott Stewart and Walter N. Meier, NSIDC)'
Tide correction now uses the ARCTIDE (v1.1) tidal model where available. FES2014b is used where ARCTIDE is not available (outside it's Arctic grid area).
Further information on ARCTIDE is provided by the reference: M. Cancet, O. B. Andersen, F. Lyard, D. Cotton, and J. Benveniste, ‘Arctide2017, a high-resolution regional tidal model in the Arctic Ocean’, Advances in Space Research, vol. 62, no. 6, pp. 1324–1343, 2018, doi: 10.1016/j.asr.2018.01.007).
DAC (Dynamic Atmosphere Correction) now used instead of IB (Inverted Barometer). The DAC includes the IB correction as well as a high frequency MOG2D barometric model forced by wind and pressure.
Mean Sea Surface (MSS) has been updated from the DTU15 to DTU21. The reference for DTU21 is Andersen, Ole Baltazar (2022): DTU21 Mean Sea Surface. Technical University of Denmark. Dataset. https://doi.org/10.11583/DTU.19383221.v1 )
