Large Scale Forcing Data - Gan



A link to the DOE ARM Archive AMIE-Gan objective analysis of large scale forcing data. The constrained variational objective analysis approach was used to derive the large-scale single-column/cloud resolving model forcing and evaluation data set from the observational data collected during ARM MJO Investigation Experiment (AMIE), which was conducted during October 2011 to March 2012 on Gan Island in the Maldives. The forcing data represent an average over the analysis domain centered at ARM mobile facility with a diameter of 300 km. Due to the lack of a sounding array at Gan Island, the forcing data for AMIE-Gan was developed based on ECMWF analyses, which were then constrained with observed surface rainfall through the constrained variational objective analysis. Three versions of the forcing data are provided, which were constrained by surface precipitation retrieved from SMART-R, S-POL, and TRMM precipitation radar measurements, respectively, to address uncertainties in surface rainfall.
