Land-Surface Atmosphere Interactions: Observations and Data Sets

IHOP/NCAR Soil Moisture, Soil Temperature, and Vegetation Observation Network

Introduction

The boundary-layer portion of the International H2O Experiment (IHOP_2002) supports its overall goal to improve convective precipitation prediction through better use and representation of water vapor in numerical weather prediction (NWP) models through estimating surface water vapor and sensible heat fluxes, characterizing the influence of surface properties on boundary-layer heterogeneity, and understanding the role that these play in the initiation and evolution of convective precipitation systems. Data collection and analysis were designed to provide benchmarks to enable improvements in the representation of land-surface and boundary-layer processes in NWP models. >more
