Description

Dear ROM SAF Data User

Issued: 2020-01-09 16:36 UTC

The ROM SAF is pleased to announce that the Interim Climate Data Record (ICDR) and Offline products now covers the period up to and including July 2019.

The month of July 2019 will be the last month where the ICDR and Offline Level 2B products (temperature, humidity, pressure) are based on ECMWF ERA-Interim as background fields in the 1D-Variational retrieval. We are currently preparing a change to using ECMWF ERA5 as background fields and more information about this upgrade will be made available in the future.

The ROM SAF product archive contains the resulting Level 1B, 2A, 2B and 2C data (atmospheric profiles), and Level 3 data (gridded monthly means) formatted as netCDF files, with a subset of the atmospheric profiles formatted as BUFR. The definition of processing levels are as follows:

Level 1A: excess phases, amplitudes, satellite orbital data (input)
Level 1B: bending angle
Level 2A: refractivity, dry temperature
Level 2B: temperature, humidity, pressure
Level 2C: surface pressure, tropopause height
Level 3: gridded monthly means of all geophysical variables

Documentation and access to the products are available at the Product Archive: http://www.romsaf.org/product_archive.php

Kind regards
The ROM SAF Team
