How land and lower atmosphere exchange heat and moisture
What it measures. A blended picture of conditions near where the land meets the air, combining many measurements into a single consistent description of surface and near-surface atmospheric properties over time.
How it's made. Assembled by merging multiple data sources of differing scales, filling gaps where coverage was sparse, and mapping everything onto a 1-degree global grid at daily or 3-hourly steps for the years 1998 to 2007.
How & where you'd use it. Gives researchers a unified record for studying how the land and lower atmosphere exchange heat and moisture across days to decades.

Official description
This product is a multi-variate data compilation that reconciles the variation scales of these multiple measurements from varies resources, merges and maps them into a comprehensive description of the near-surface atmospheric properties together with the land surface property variations on diurnal-to-decadal time scales. Many of these data products, especially those based on surface measurements, are spatially and/or temporally sparse or incomplete in coverage, so procedures were developed to fill missing values. The data product is comprised of a sequence of daily global files, where quantities are mapped into 1.0-degree equivalent equal-area grid, with time sampling is reported at daily or 3-hourly intervals. The time period overlap among the products covers 10 years from 1998 to 2007.
