Processing Baseline
(S3A / S3B)

IPF Version

Changes

Date of deployment

2.47 / 1.19

SL_1 v06.16
SL_2 v06.14

  • S3A SL_2 update
    • The LST retrieval algorithm has been generated with a new set of retrieval coefficients which utilises an enhanced approach to simulating the across track variation in LST performance when generating the coefficients.
    • Implementation of the new retrieval coefficients has improved the performance of the S3A LST product with respect to intercomparison against operational LSA SAF SEVIRI LST
  • S3B SL_2 update
    • The LST retrieval algorithm has been generated with a set of retrieval coefficients which utilises an enhanced approach to simulating the across track variation in LST  performance when generating the coefficients.
    • Implementation of the retrieval coefficients has improved the comparability between S3A and S3B LST during the Tandem Phase
