Project Title:Long-Term Multi-Sensor Record of Fire Disturbances in High Northern Latitudes
Project Lead: Tatiana Loboda, University of Maryland
Project Funding: 2013 - 2016
NASA (agency representative: Diane Wickland)
Project Type:NASA -- joined ABoVE in 2013
Solicitation:NASA: Pre-ABoVE: Terrestrial Ecology (2012)
Abstract: The greatest rise in global temperature is occurring in High Northern Latitudes (HNL) above 60°N and this recent warming trend is projected to continue. Wildfire is the main disturbance agent in this ecosystem and a major emerging issue identified by the North Slope Science Initiative. Although much research has been done in the forested areas of ...

Product Title:  ABoVE: Study Domain and Standard Reference Grids
Description:  The Arctic - Boreal Vulnerability Experiment (ABoVE) has developed two standardized spatial data products to expedite coordination of research activities and to facilitate data interoperability. First, the ABoVE Study Domain encompasses the Arctic and boreal regions of Alaska, USA, and the western provinces of Canada, North America. Core and Extended study regions have been designated within this Domain and are provided in both a vector representation (Shapefile) and a raster representation (GeoTIFF at 1,000-meter pixel resolution). Second, a Standard Reference Grid System has been developed to cover the entire Study Domain and also extends to the eastern portion of North America. This Reference Grid is provided as a nested pair of polygon grids at scales of 240- and 30-meter spatial resolution. A shapefile is provided for each grid. Note that the designated standard projection for the all ABoVE products is the Canadian Albers Equal Area projection.

Product Title:  Cloud Climatology for HNL
Description:  For high northern latitudes (HNL), a set of cloud climatology products will be delivered based on MODIS observations from Terra and Aqua: 1) a 1 km dataset of 10-year (from 2003 – 2012 ) earliest, mean, and latest dates of snow establishment and melt; and 2) a 1km dataset of 10-year (from 2003 – 2012 ) mean daily, 10-day, 20-day, monthly, and early/late season fractional cloud cover.
Expected Users:  Scientists and policy makers for Arctic and Boreal regions.

Product Title:  Active fire detection record compilation
Description:  Three datasets will be used to develop an extensive record of active fire detections in the high northern latitude (HNL) regions studied: 1) a MODIS record of active fire detections by year for 2001-2015 (Pan-Arctic HNL); 2) a VIIRS record of active fire detections by year for 2012-2015 (Pan-Arctic HNL); and 3) an AVHRR record of active fire detections over North American HNL regions from 1982-2003 and Pan-Arctic HNL as data is available. Finally, a document detailing quantitative inter-comparison of all active fire detection products within the delivered suite of datasets (includes MODIS vs. VIIRS, MODIS vs. AVHRR, and various AVHRR data product comparisons) will be provided. These coarse resolution active fire detection products from AVHRR, MODIS, and VIIRS will be stored as point vector shape files in a geographic coordinate system (lat/lon) where points will represent the center of the detection pixel. Active fire detection records will be compiled by year and by source (e.g. MODIS_2001_NA_af.shp) and will preserve all original source attributes including detection time, source satellite (e.g. Aqua or Terra for the MODIS instrument), and sensor appropriate detection criteria such as temperature brightness values. Active fire detections datasets will provide auxiliary information for the ecological studies and are unlikely to be ingested in models directly.

Product Title:  Coarse resolution burned area mapping
Description:  A course resolution high northern latitude (HNL) burned area product will be developed using 1) yearly records of burned area from AVHRR (1982 – 2003 for North America and when available for Northern Eurasia); 2) yearly records of burned area from MODIS (2001 – 2015 for the Pan-Arctic region); and 3) yearly records of burned area from VIIRS (2012 – 2015 for the Pan-Arctic region). Additionally, an accompanying document detailing the inter-comparison of the available coarse resolution datasets and validation against moderate resolution (Landsat-based) assessments will be provided. Gridded binary burned/unburned datasets from AVHRR, MODIS, and VIIRS will be compiled in yearly instrument-specific GeoTIFF files in a chosen equal area projection (e.g. MODIS_2001_NA_ba.tif).

Product Title:  Moderate resolution burned area mapping and characterization from optical data
Description:  Using the Landsat archive, a record of burned area from 1984 – 2015 will be developed for all high northern latitude areas (HNL). Then, these burned areas will be characterized using burn severity metrics such as the delta Normalized Burn Ratio (dNBR) and Tasseled Cap Brightness (TCB). The burned area product will be provided as gridded binary burned/unburned products at 30 m resolution while the fire impact severity will be stored in the GeoTIFF format as 30m grids.

Product Title:  Fire progression mapping
Description:  Yearly Pan-Arctic maps of “fire progression” (date-of-burning) within moderate resolution-based burned areas (from 2001 – 2015) will be developed based on the MODIS and VIIRS active fire detections (see active fire product above). Also, yearly “residual burning” (number of days after the first detection) maps will be developed across this same spatial and temporal region using MODIS and VIIRS datasets. Where possible, AVHRR-based “fire progression” maps will also be developed. The datasets will be stored in the GeoTIFF format.
