Changes

Date of deployment

2.61 / 1.33

SL_2 v06.16

2.59 / 1.31

SL_1 v06.17

• Revised ortho-regridding of all channels and revised geo-referencing of SLSTR F1 fire channel
• Improved geometric calibration for the oblique view
• Improved S7 BT upper limit, temporal
• Interpolation of ECMWF meteorological fields
• Improved quality checks during decontamination and black body crossover tests
• Removal of the c stripe (time domain integrated) from product, improved flags, and update of several NetCDF variable attributes.
• Baseline collection (parameter within the filename) has been incremented from 003 to 004 due to the implementation of the new regridding and the change in the product format.

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
