Short Bio: Dr. Wilfrid Schroeder is an Assistant Research Scientist with the Earth System Science Interdisciplinary Center (ESSIC) at the University of Maryland in College Park, MD.

I received the B.Sc.degree in Meteorology and the M.Sc. degree in Environmental Engineering from Rio de Janeiro Federal University, Brazil, in 1998 and 2001, respectively. In 2008 I received the Ph.D. degree in Geography from the University of Maryland, College Park. During 2000-2004 I was a full-time consultant with the United Nations Development Program in Brazil working on the implementation of a satellite fire monitoring system for Amazonia in collaboration with the Brazilian National Institute for Space Research (INPE). My research activities are focused on the validation and refinement of satellite active fire detection algorithms, and on the use of the multi-resolution data for studying spatial and temporal trends of fire activity and associated emissions at different scales. I have gained experience working with multiple airborne and spaceborne fire data including : the FireMapper (USFS) and AMS (NASA) airborne sensors, Landsat 5 & 7, ASTER, CBERS, MODIS, AVHRR, DMSP, TRMM, and GOES. I am currently involved in the following research projects: (i) validation and refinement of the current MODIS Fire and Thermal Anomalies product using multi-source fine resolution reference fire data; (ii) reprocessing of GOES East imager data and creation of a stable active fire data record and emission inventory for South America; (iii) algorithm development and early assessment of NPOESS/VIIRS and GOES-R ABI fire products using data simulation; (iv) quantification of active fire characteristics (size, temperature, radiative power) using multi-resolution airborne and spaceborne imagery.

Title of Presentation: Monitoring biomass burning activity at landscape to global scales using multi-resolution satellite data: algorithm developments and data application

Abstract: This talk will focus on the work being done to validate and refine widely used satellite active fire detection products using a variety of fine resolution imagery and data simulation techniques. The material presented will cover the current MODIS and GOES Imager fire products and the future NPOESS/VIIRS and GOES-R ABI instruments, and the creation of quality information that can be used to build consistent longer term active fire data records. Major implications resulting from the use of fire data sets of different spatial and temporal resolutions will also be addressed.
