SAF objectives

The ROM SAF generates and archives high-quality GNSS Radio Occultation (RO) data for Numerical Weather Prediction (NWP) applications and specific climate application areas, through the exploitation of satellite measurements with state-of-the-art algorithms, to derive information about the atmosphere and climate variables of the Earth system. The ROM SAF is also engaged in developing an RO processing software package containing modules for processing of RO data and for assimilation of RO data in NWP models.

The activities encompass continued developments of the processing algorithms, in order to enhance the information of atmosphere variables and for improving the products. Raw GNSS radio occultation data are calibration-free, with known assumptions, and are also well-suited for climate monitoring and trend studies. The applications cover construction of an accurate climate data record database with known error characteristics of the data.
