8 GFSAD Documentation ATBDs / NASA ESDIS Data Template / Product Quality Checklist

9 GFSAD ATBDs  The ATBD(s) should:  Be a clear description of the algorithms used to generate the products.  Be understandable to the intended users of the products.  Be applicable to the version of the product delivered to the DAAC.  Datasets that use inputs for which ATBDs are available can just point to those ATBDs; but there needs to be documentation on how the delivered products were generated using those inputs.  For example, using MODIS EVI as in input to a MEaSUREs product algorithm  The form and review process used for an ATBD is at the discretion of the funding NASA Program Manager.  Peer reviewed articles as ATBDs – Five requirements: 1. Background/Intro 2. Algorithm descriptions 3. External dependencies/product interdependencies 4. Approach to validation/uncertainty analysis 5. Anticipated/known issues

10 GFSAD NASA ESDIS Data Template  Requirements  Project Overview  Project Objectives  Science Objectives  Mission Summary  Instrument Overview  Project Data Flow  Mission Operations  Science Operations  Products  For Each Product  Science Data Product Summary  Associated Archive Products  Special Considerations Caveats / Known Issues / Micro Issues (e.g. crop failure/replant)

11 GFSAD NASA Product Quality Checklist  Each project is asked to coordinate with its partner DAAC to complete checklists for ESDRs or groups of ESDRs as they are completed and provided to the DAAC for archive and distribution. The completed checklists will then document the completion, delivery to the DAAC, archive, and preparation for or beginning of distribution of the ESDR(s) to the science community. The products documented in the checklists should be those new ESDRs developed by the project under MEaSUREs funding.  The checklists would be completed for each ESDR, or group of ESDRs that are handled as a package by a project or DAAC. The project and DAAC can split out the tables (i.e. clip off the introductory text) and make as many copies of the tables as needed, and fill in responses for each ESDR or group of ESDRs.  The response to each question (in the box following each question) would be yes, partially, or no. Explanations of a ‘partial’ response or any other explanatory comments would be entered into the ‘comments’ row below each question. Then comments may be as long as needed; as text is entered into the comment fields they will grow to accommodate it, and the number of pages occupied by the checklist will grow as needed.

17 GFSAD LP DAAC WMS  LP DAAC will not continue development of a GFSAD WMS:  Considering Justin’s work, provisional needs are met (?).  If there exist reasons to continue:  What are the (new/not included/missing) features ?

18 GFSAD GCE Versions  GCE V0.0, 1.0, 2.0, 3.0  Existing journal references exist for V0.0 & V1.0.  Known requirement to re- document V0.0 & V1.0 products.  Team versions vs algorithm versions = confused users.  LP DAAC Versions  GFSAD1KMCD V1.0  GFSAD1KMCM V1.0  GFSAD250M<> V1.0  GFSAD30M<> V1.0  Going Forward  LP DAAC recommends eliminating current team versions.  Instead, describe the products, such as “GFSAD Crop Mask at 1KM”, “GFSAD Crop Dominance at 1KM”, “GFSAD at 250M”.  Not recommended, a compromise is GFSAD1KMCD (GCE V1.0)

20  Note:  “…develop a checklist of a small number of questions that represented progress in the product quality area. We considered product quality to be a combination of scientific quality and the completeness of associated documentation and ancillary information. The responsibility for the product quality is shared between the projects generating the ESDRs and the DAACs that eventually archive and distribute them.”  Each project is asked to coordinate with its partner DAAC to complete checklists for ESDRs or groups of ESDRs as they are completed and provided to the DAAC for archive and distribution. The completed checklists will then document the completion, delivery to the DAAC, archive, and preparation for or beginning of distribution of the ESDR(s) to the science community.

21 Provisional Data Distribution GFSADCD1KM aka GCE V0.0 The GFSAD Global Crop Dominance at nominal 1KM(GFSADCD1KM), aka Global Cropland Extent 1km Crop Dominance (GCE V0.0), provides information on the spatial distribution of the five major global cropland types (wheat, rice, corn, barley, and soybeans), which occupy 60 percent of the total cropland area at nominal 1km. The map is produced by overlying the five major cropland types of the world produced by Ramankutty et al. (2008), Monfreda et al. (2008), and Portman et al. (2009) over the remote sensing derived global irrigated and rainfed cropland area map of the International Water Management Institute (IWMI; Thenkabail et al., 2009a, 2009b, 2011). The GFSADCD1KM product is an 8 class digital product that provides, at nominal 1 km, information on global: 1. Cropland extent\areas; 2. irrigated versus rainfed cropping; 3. Crop dominance; and 4. Cropping intensity (single, double, triple, and continuous crops). Geographic Extent: Global Map Projection: Geographic (Lat/Long) Datum: World Geodetic System 84 Raster Type: Thematic Spatial Coordinates: Min/Max Longitude -180 to 180, Min/Max Latitude -90 to 90 Temporal Coverage: Nominal Year 2000 Columns: 40430, Rows: Size: 845MB

22 Provisional Data Distribution GFSADCM1KM aka GCE V1.0 The GFSAD Multi-Study Global Crop Mask (GFSADCM1KM), aka Global Crop Extent (GCE V1.0), provides the spatial distribution of a disaggregated five class global cropland extent map derived at nominal 1km based on four major studies: Thenkabail et al. (2009a, 2011), Pittman et al. (2010), Yu et al. (2013), and Friedl et al. (2010). Classes 1 to Class 5 are cropland classes, that are dominated by irrigated and rainfed agriculture. Class 4 and Class 5 have minor/very minor fractions of croplands. GCE 1KM Multi-study Crop Mask is a 5 class digital product that provides, at nominal 1 km, information on global: 1. cropland extent\areas, 2. irrigated versus rainfed cropping. There is no crop type or crop type dominance information. Cropping intensity (single, double, triple, and continuous crops) can be obtained for every pixel using time-series remote sensing data. Geographic Extent: Global Map Projection: Geographic (Lat/Long) Datum: World Geodetic System 84 Raster Type: Thematic Spatial Coordinates: Min/Max Longitude -180 to 180, Min/Max Latitude -90 to 90 Temporal Coverage: Nominal Year 2000 Columns: 40457, Rows: Size: 25.67MB
