Fire Detects from the Moderate Resolution Imaging Spectroradiometer (MODIS)
Satellite Services Division receives MODIS fire products from NOAA's
MODIS Near
Real Time Processing System, run by it's sister division -- the
Information Processing Division. The MODIS instrument flies
onboard the NASA TERRA and AQUA satellite, and the fire algorithm was developed
by the MODIS Fire and Thermal
Anomalies team.
The fire product recieved by SSD is in large (~13mb) HDF files. We extract
the fire positions and confidence values and place them into comma-delimited
tables that it can
be easily read into a Geographic Information System (GIS) as table data.
Users should note:
- This data is generated by an automated algorithm and is placed on
the web page in near-realtime. It has not been quality controlled. Validation
efforts are only beginning.
For a quality controlled product, users are referred to the
Hazard Mapping System (HMS) product created
by SSD satellite analysts.
- Fire locations represent the approximate location of the fire pixel
and do not represent the actual fire size. The MODIS instantaneous
field of view at nadir for the channels used to make the fire product is
1x1km, but the fire phenomena may be much smaller than that.
- We post this data as soon as we receive it, but the Near Real Time
Processing System is not considered operational.
We do not guarantee 24/7 access to this data at this time.
- If no fires are detected for a given pass, a file is not placed on the serve
r.
The most recent MODIS fire detects, as well as the
other layers that make up the HMS Fire and Smoke Product,
can best be viewed through our
SSD Fire Web-GIS page.
