EUMETSAT MPEF Active Fire Monitoring product Monitoring Validation

EUMETSAT MPEF Active Fire Monitoring product — Monitoring & Validation Sauli Joro EUMETSAT Training Workshop ― “MSG Land surface Applications: Drought & Fires” NIMH, Bulgaria, 07 -11 September 2009 Slide: 1 12/22/2021

About the MPEF System • MPEF has three processing chains: Operational (OPE), Validation (VAL), and Long Term Validation (LTV) • Each of the processing chains has two instances (A & B) — one for Met-8 (Rapid Scanning Service) and one for Met-9 (Full Earth Scan) • OPE and VAL have different image feeds, OPE and LTV uses the same image feed • Limitation of the system: re-prosessing NOT possible at the moment (RMPEF project on-going) • This monitoring & validation scheme is applicable to ALL MPEF products Slide: 2

System Monitoring • Meteorological Operations Division (MOD) at EUMETSAT has a web-based tool to monitor the number of Fires and Possible Fires Meteosat-8, RSS Meteosat-9, FES The purpose of this tool is to monitor the SYSTEM, not the PRODUCT Slide: 3 Met-8 operational Met-9 safe mode

Algorithm Monitoring • MPEF system has a Product Quality Monitoring tool, which allows visualisation of products together with SEVIRI images — only the last 24 hours is available, after which the product is archived • “In-depth” analysis of a case requires always user written scripts and tools (IDL, PV-WAVE) • Offline database offers a possibility for a closer algorithm monitoring, great for spotting anomalies in daily cycles etc… Slide: 4

Algorithm monitoring — 2005 vs Oct 2008 20: 30 UTC Slide: 5 ~15 UTC

Night time fire detection limited? (version Oct 2008) • When in its more active state Etna serves a stable source of heat — good for algorithm monitoring! • During the daytime on 21 Aug, all four pixels were detected as “Fire”, after sunset only one pixel, between 04: 30 UTC and 06: 00 UTC none 3. 9 µm RSS Slide: 7 04: 05 UTC 22 Aug 2008 04: 35 UTC

Algorithm Monitoring — Oct 2008 vs Jul 2009 06: 00 UTC Slide: 8 ~15: 00 UTC

Algorithm Monitoring – Oct 2008 vs Jul 2009 06 UTC anomaly consists of probable fires Slide: 9

Algorithm Validation • In order to use the word “validation” one should have a “ground truth” available • No ready made tools available, “validation” relies heavily on visual inspection of a product together with time series analysis • Information on occurring fires is difficult to get — many countries have their own databases, which are not necessarily available to the outside world • MPEF FIR product can be, though, compared against other fire products using other instruments (MODIS) Slide: 10
