Investigating Seasonal and Interannual Variability of Latent Heat Flux Using a High Resolution Satellite Product
Abstract
Latent heat flux (LHF) plays a crucial role in the global atmosphere-ocean energy balance. Many efforts have recently been underway to produce high quality global measurements using satellite-based instruments. This study will introduce a new satellite based product with sub-daily, quarter-degree resolution. The near-surface specific humidity fields are derived from a 3-hourly product developed using the Jackson et al. (2006) retrieval method. An empirical orthogonal function reconstruction method has been employed to interpolate missing data. The wind speed product used is the National Climate Data Center (NCDC) Blended Winds product. Together, these parameters are used with a diurnally varying sea surface temperature product and the COARE 3.0 algorithm to produce the LHF product. This study will provide analysis of this product and comparisons with other currently available products. The primary focus will be on determining how this product differs from others on seasonal and interannual timescales.
