The Global FIRE Product, 1992-1993, from JRC
Entry ID:
SAI_JRC-Global_FIRE
|
Summary
Fire is a process, which given the right vegetation and meteorological
conditions, can be found in almost any part of the globe. In order to
understand and quantify the impact of fire on ecosystems and
atmosphere, there is a need to provide and analyse data on the spatial
and temporal distributions of fire at a global scale.
The fire products described ... here are derived from space observations
done by the AVHRR sensor on board the NOAA satellites. They provide a
coherent, consistent data set on biomass burning events, at a global
scale, for each day processed. Two product types are produced. A
raster file giving number of fires detected in a 0.5 degree x 0.5
degree grid cell for a seven day period and a binaryfile giving the
latitude and longitude positions in a platte-carre projection for each
fire detected in the original 1 km data, per day.
The HRPT/LAC data is collected from a network of 26 receiving stations
and converted into aconsistent archive. This is carried out by the EROS
Data Centre [EDC] and the European Space Agency [ESA/ESRIN]. The data
is then "stitched" into orbital segments. There are on average14
orbital segments for complete global coverage. For further details see
Eidenshink and Faundeen [1995].
Each raw image strip is processed to produce a file containing the
lat/lon positions of detected potential active fires. The steps in
processing are as follows:
[i] cloud mask: the data is screened using a cloud detection
algorithm, any pixels being detected as clouds are eliminated from
further processing
[ii] water mask: A land sea mask created from the World Data Bank
[WDB] II vector coastline at a resolution of 2 minutes is applied to
the data in order to remove water areas and hence speed up processing
[iii] desert mask: permanent desert areas are removed by applying a
mask derived from Olson World Ecosystem Classes, version 1.4D.
[iv] fire detection: A contextual algorithm is used for fire
detection.
The global fire product is intended for use in applications studying
phenomena at a global scale. It offers a consistent product in that
the same detection algorithm is used throughout. The raster product is
produced with the atmospheric science community in mind as it is
produced at a scale which is consistent with a number of general
circulation models. The daily product maintains the full 1km
resolution of the original data, therefore favouring ecosystem studies
where the localisation of individual fire events is important.
Pending further development, this could become a standard thematic
product.

Quality
Fires may be erronously flagged in certain situations where there is a
step change in the thermal signal as recorded in channel 3 of
AVHRR. The environments in which this may be a problem are: along
coastlines, inland water ways, desert boundaries, mountain-plain
interfaces. The locational accuracy is +/- 5 km at nadir and
deteriorates at wide viewing ... angles. Care should be taken when using
the data for applications where precise location is an issue. An
improved processing chain, under implementation at GVM, will provide a
location accuracy of +/- 1.5 km.
The quality depends on 1)fires detection which must manage with
problems of hot areas and sunglint 2)cloud dedection 3)location
accuracy which is +/- 1.5 Km.
Access Constraints
End-users external to GVM can have access to the data and make use of
it in their own field of research and/or application only if they
fullfill the use- constraints listed below.
Use Constraints
When the data set is derived from results already published in
conferences or journals, the external user must agree with MTV on the
correct form of reference. If it is derived from results not yet
published, the external user and MTV should agree on a co-author
work. Special agreement from IGBP-DIS is required.
