HDF-EOS V2 MODIS L3 Monthly 500m Burned Area Intermediate Product File Specification
Original Version 5.0.0 (October 2004)
Product ID(s): MCD45A2 (L3 Monthly 500m Burned Area Intermediate)
Description:
This process makes Monthly 500m Burned Area Intermediate Product MCD45A2
from MODIS daily 500m Surface Reflectance Product MODHDFSR and
- read MODIS daily 500m surface reflectance and angle data from time series of
daily MODHDFSR files (in order), check QA and snow, and store valid observations only;
- moving window BRDF inversion;
- predict subsequent observations and calculate Z scores;
- find burn candidates
- reject false detection through spectral constraint, and temporal consistency and presistency check
- output top three candidate burn dates and associated info for the cleaning phase
- both fowrad and backward prediction and detection implemented

Generic Constructs
ECS Metadata Strings:
Notes: "FR" is an abbreviation for "FREE_RANGE".
"D/T" is an abbreviation for "DATE/TIME"
(A) implies that multiple values are stored within a
single array.
A value of "Variable" indicates that this value will vary
according to the granule being processed.
"M" means class M.

* Note that MeasuredParameter group has

* Basically one needs to put DataField (SDS) names to PARAMETERNAME
* and put corresponding QA metadata to QAFlags and QAStats.
* If one has only QA metadata for whole product, instead for each
* and individual DatFiels (SDS), it's suggested to put product
* name to PARAMETERNAME.
