Weekly/diurnal emissions can be modeled by applying the TIMES (Temporal Improvements for Modeling Emissions by Scaling, Nassar et al. 2013) temporal scaling factors to the ODIAC monthly emission fields. The scaling factor is defined on a 0.25 x 0.25 degree. The gridded scaling data product can be downloaded from the web site of the Oak Ridge National Laboratory.
