Long-Term Data Collection and Empirical Background Temperature Modeling
Abstract
At the Research Institute, U.S. Army Topographic Engineering Center (TEC) we are developing empirical models to predict background surface temperatures and thermal contrasts, using continuous, long-term data collection in various climates. We are using a type-day concept to bound and group the values of radiation and other meteorological parameters into typical, somewhat unique weather conditions. Type-days are differentiated mainly by limits on integrated short and long wave incoming radiation, which portray sky cover and atmospheric conditions. The inputs to the models are climate, season, sky cover and whether the bare soil is 'wet' or 'dry'. We believe that existing, energy budget, surface temperature models are too complex in input variables and in operation, and that they cannot be simplified for tactical use. We also think that there is insufficient joint meteorological, radiometric and surface temperature data available.
