On average, FRP derived from SEVIRI is underestimated between 30% and 50% when compared to MODIS (ROBERTS and WOOSTER, 2008), therefore, FRP estimated by SEVIRI was corrected in 40% of the monthly average of MODIS FRP estimates.
Figure 3 shows total number of fires detected by MODIS and SEVIRI sensors in sugarcane crop areas of Sao Paulo state between 2008 and 2014.
For SEVIRI active fire product, total fires in 2008 were below expected, which can be explained by the fact that FRP-PIXEL started providing data in April of 2008, therefore, fires between January and March of 2008 were not detected.
As expected, SEVIRI based active fire product detected more fires than MODIS active fire products, once it has a higher temporal resolution.

Figure 3 shows the annual mean percentage of cooking days, along with monthly means from July and January, from both SEVIRI and surface observations in the Sahel (other months are shown in supplementary Figs.
The Nile is easily identified in Egypt and Sudan in the SEVIRI plots; this is likely from persistent cloud-flagging errors as well as real clouds.
This climatology of sunshine from SEVIRI and SYNOPs has a number of practical implications beyond solar cooking--for example, it could be used to examine the feasibility of solar electricity generation.
Alongside SEVIRI, the Anglo-European Astrium joint venture is responsible for a range of operational and planned satellite meteorological instrumentation packages that include the Advanced Microwave Sounding Unit (AMSU)-B, the Humidity Sounder for Brazil (HSB), the Advanced Scatterometer (ASCAT), the Microwave Humidity Sounder (MHS) and the Atmospheric Laser Doppler Instrument (ALADIN).
Alongside MSG-1, SEVIRI is to be fitted aboard the forthcoming MSG-2 and -3 vehicles.
