The algorithm updates include the following:

  • LPRMv6.1 is used for all passive sensors. This includes improved inter-calibration and improved flagging of snow conditions.
  • A new ASCAT version is used which includes optimised cross over angles for vegetation correction and improved snow / frozen flagging.
  • Cross-flagging of frozen soils is implemented to take advantage of flagged observations in all datasets.
  • The period for which TMI is used has been extended to 2015 and FY-3B and GPM are included for the first time.
  • Gap filling of SNR data is undertaken per land cover class rather than globally.
  • Break-adjusted COMBINED product provided as an experimental product using ERA5 as a reference. See Preimesberger et al. (2021) for further details.
