AB  - The FREEVAL project answered EUMETSAT invitation to tender (ITT) No 06/794 Evaluation of a Fire Radiative Power Product derived from Meteosat-8/9 and Identification of Operational User Needs. The core work of this project was to evaluate the efficacy of a retrieval algorithm used to identify actively burning fires and estimate their fire radiative power from SEVIRI observations of fire-affected regions, and determine the effectivness of the retrieved observations. This algorithm was developed by M. Wooster and his colleagues at King’s College London (KCL), and had been selected by EUMETSAT for implementation prior to the start of FREEVAL. During FREEVAL, EUMETSAT implemented the algorithm in a prototype operational processing chain, aided by advice from KCL and with some algorithm changes being necessary in that environment. The assessment of algorithm retrieval accuracy covered several aspects and was tailored to provide sufficient information so that an operational readiness report (ORR) can be issued and the data product can be generated with full specifications. The validation of the SEVIRI fire radiative power (FRP) product considered three main aspects: 1) theoretical performance of the FRP algorithm, 2) accuracy and performance limitations due to the SEVIRI instrument and to the level 1.5 data characteristics from which all SEVIRI geophysical products are currently derived, 3) performance of the specific FRP algorithm implementation at the Land Surface Analysis Satellite Applications Facility (Land-SAF). Validation was performed through radiative transfer modelling, through product analysis and cross-comparison at the pixel, fire, and grid-cell (e.g. 1$^{\circ}$ x 1$^{\circ}$) and regional basis, including comparisons with independent data products. In many cases, data from the EOS Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) was used as the comparison dataset, since FRP can also be derived from the measurements of this sensor, but the analysis also included data from other sensors and platforms.
