* Earth System Science

Current headache...
----------------------------------------
The main goal is to develop a long-term (1981-2011) burnt area map database at 0.05º spatial resolution during a 16-day period. The burnt area product initially will be used to create a fire regime global synthesis map and eventually as well to improve estimates of pyrogenic emissions of greenhouse gases, to analyse fire-climate relationships, and to assess the performance of process-based fire modules of dynamic global vegetation models (DGVMs).

The main input of the burnt area identification algorithm is the Advanced Very High Resolution Radiometer (AVHRR) long-term data record (`LTDR <http://ltdr.nascom.nasa.gov>`_) which comprises a daily global atmospherically-corrected surface reflectance dataset at 0.05º spatial resolution. The AVHRR-LTDR is available for the period 1981-1999, in order to complete the surface reflectance time series until 2008, the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor will be used. However the use of another sensor implies, either a sensor intercalibration or a band conversion to a common wavelength, a commonly used methodology is the narrow to broadband transformation. The latter option was implemented using the narrowband to broadband conversion formulae for AVHRR developed by Liang (2001), this will allow to integrate MODIS and AVHRR data in three spectral broadband ranges, namely the solar spectrum (400-3000nm), the visible (400-700nm) and the near- and shortwave infrared (700-3000nm). All daily AVHRR acquisitions were converted to broadband for the chosen prototype year, 1998.
