Bowtie effect occurs like MODIS
Exchange email conversation with Chris Justice to add
Thailand into VIIRS Fire Products calibration as we have
been using MODIS Fire Products from
FIRMS for daily fire control management since late 2006.
He sent message to Ivan Csiszar, Wilfrid Schroeder, Evan
Ellicott, Louis Giglio on 26 Jan 2012 as
“……Yes validation in Thailand would be a good thing in the
framework of GOFC GOLD.
Thanks

In conclusion
It seems that VIIRS has the same problems as both
MODIS have.
We will have to use VIIRS fire products for Forest Fire
Control Management in Thailand as we already use
the MODIS Fire Products daily (when it begins to feed
into FIRMS).
Hopefully the Principle Investigators of VIIRS Fire
Products will include Thailand as one of their
calibration sites.
Thank You Very Much
