MODIS Combined (Terra + Aqua) 4-day composite L4 500m FPAR,LAI (MCD_PR15A3) Document Revision: 10.11.2013 PGE Version : 6.0.5 PGE Release : 06.09.2014 _SS_ Product ID(s): MCD15A3H MODIS Terra + Aqua Gridded 500m FPAR and LAI (4-day composite) Description: MODIS Level 4 500m Combined Fraction of Photosynthetically Active Radiation (FPAR), and Leaf Area Index (LAI). This 4-day combined algorithm produces a single FPAR,LAI tile product from at least one candidate daily MOD15A1 and one MYD15A1 FPAR,LAI products produced by PGE33. These are tiled using Sinuoidal grid. All FPAR and LAI data is stored in HDFEOS v.2.1.x files, as separate grid fields within the MOD_Grid_MCD15A3H grid object. Note that the LAI product range of {0..100} should be interpreted biophysically as ranging from {0...10.0}, with one digit of implied precision. The HDFEOS file format produced by PGE 94 is the final 4-day FPAR, LAI composite product archived at EDC. Significant changes: -- In collection 6 we have changed the input to MOD15A1H/MYD15A1H, 500m daily LAI/FPAR and the output is 500m 4 day LAI/FAR composites. -- In version 5.0.0 we have fixed all metadata issues as reported by LDOPE. We have also updated all lookup tables. We are introducing weights when calculating average LAI over distribution of solutions. Additionally we have added two new SDSs to the product: FparStdDev_500m and LaiStdDev_500m They track the FPAR and LAI standard deviation for pixels produced by the main (R-T) method. -- There is a new FparLai_QC bit layout based on the changes recommended by LDOPE: BITFIELDS ------------- 0,0 MODLAND_QC bits '0' = Good Quality (main algorithm with or without saturation) '1' = Other Quality (back-up algorithm or fill values) 1,1 SENSOR '0' = Terra '1' = Aqua 2,2 DEADDETECTOR '0' = Detectors apparently fine for up to 50% of channels 1,2 '1' = Dead detectors caused >50% adjacent detector retrieval 3,4 CLOUDSTATE (this inherited from Aggregate_QC bits {0,1} cloud state) '00' = 0 Significant clouds NOT present (clear) '01' = 1 Significant clouds WERE present '10' = 2 Mixed cloud present on pixel '11' = 3 Cloud state not defined,assumed clear 5,7 SCF_QC (3-bit, (range '000'..100') 5 level Confidence Quality score. '000' = 0, Main (RT) method used, best result possible (no saturation) '001' = 1, Main (RT) method used with saturation. Good,very usable '010' = 2, Main (RT) method failed due to bad geometry, empirical algorithm used '011' = 3, Main (RT) method failed due to problems other than geometry, empirical algorithm used '100' = 4, Pixel not produced at all, value coudn't be retrieved (possible reasons: bad L1B data, unusable MOD09GA data) Versioning: We currently version-stamp our source code, ancillary files and product files with an identical version and release-timedate stamp, called UM_VERSION. Users may extract this version stamp from any product or ancillary file using a command like this: ncdump -h MOD15A2_ANC_RI4.HDF | grep UM_VERSION. The latest certified codeset carries this version stamp as a global file attribute in the product files, ancillary files, and within the executable: UM_VERSION = UM_VERSION = "U.MONTANA MODIS PGE34 Vers 5.0.0 Rev 4 Release 10.01.2004 23:59" Point of Contact: Petr Votava (Software Development and Maintenance) votava@ltpmail.gsfc.nasa.gov Nikolay Shabanov (Science) shabanov@crsa.bu.edu Principal Investigator(s): Ranga Myneni Department of Geography 675 Commonwealth Avenue Boston University Boston, MA 02215 Email: rmyneni@bu.edu Voice: (617) 353-5742 Fax : (617) 353-8399 ============================================================================ Generic Constructs ECS Metadata Strings: Notes: 1.

This is done to help assure that the executable is run with a compatible ancillary file, and to provide a single comprehensive versioning stamp common to our executables, product files and ancillary files. Attribute Name: ENGINEERING_DATA Description: This text attribute contains a development log of various internal session metrics. The attribute "ENGINEERING_DATA" is created for all runs, but is only populated if the LCMP_PCF_ENGDATA runtime switch is set to "1" in the PCF file. If the LCMP_PCF_ENGDATA switch is set to "0", the contents of the attribute is "(none-available)". It's purpose is to more effectively enable to to perform post-processing quality control at the SCF, when we have access to just the HDFEOS product files and not the original ECS session logs. ========================================================================================= NEW PGE94 OPTIONAL BROWSE FILE GENERATION ========================================================================================= --Note that PGE94 now optionally produces a 5km BROWSE (or COARSE) product for each data layer, triggered by the .pcf file runtime input, LCMP_PCF_BROWSE, as a stand alone HDFEOS file.
