OSI SAF updated Atlantic High Latitude radiative flux products available on EUMETCast from 4 June 2020.

Last Updated

23 February 2023

Published on

20 May 2020

The products are:

  • Atlantic High Latitude Downward Longwave Irradiance (AHL DLI, ID: OSI-301-b)
  • Atlantic High Latitude Surface Solar Irradiance (AHL SSI, ID: OSI-302-b)

They are new versions of the current OSI-301 and OSI-302 products. The main changes are algorithm improvements to extend the products over sea ice and overall quality improvement. Also, the two products are now delivered in one common netCDF4 file, instead of two separate GRIB files. Both products have operational status.

More details, including documentation (user manual, validation report, ATBD) and access to quicklooks, are available here:
