Cloud Mask - NWC SAF
• Uses SEVIRI data and other auxiliary inputs
– Mandatory channels: R0.6μm, T3.9μm, T10.8μm, T12μm
– Other optional channels
• Multispectral thresholding techinque applied pixelwise

DSSF & DSLF Algorithms
10
FRP Algorithm
• Detect pixels containing
active fires
– Thresholding based on
surface reflectance and
brightness temperature
values
• Input data
– VIS + MIR + TIR
– NWC SAF Cloud Mask
– Landcover
• Report
– Time & Location
– Radiative Power (MW)
• Carbon cycle
11
We are Copernicus
• CGL - Copernicus Global Land
– Bio-geophysical products
– Global scale
– Energy, Water, Vegetation
• CAMS - Copernicus Atmosphere
Monitoring Service
12
Taking Advantage of the
NOAA & JMA GEO Satellites...
MTSAT/
Himawari
MSG
GOES E
... to obtain geo-ring products!
13
Geo-ring LST Retreivals
Only one TIR channel is available
thus
different formulation is applied!
14
Geo-ring LST Products
• Hourly LST
• 10-Daily Composites of LST
• TCI (Thermal Condition Index) based on a multi-year climatology
15
Additional Geo-ring Products
• DSSF
• DSLF
• Evapotranspiration
DSLF
16
CAMS - FRP extended to
Americas
• Using data from
GOES East and
West
• Complement
LSA SAF's FRP
product
