General Overview

ARM receives two different types of ECMWF products. Diagnostic data derived from ECMWF model runs are especially generated for ARM analysis for the ACRF facilities. In addition, ARM purchases more detailed ECMWF products covering a larger area for the TWP sites. These data can only be distributed to ARM scientists. ARM scientists who obtain these data must agree to acknowledge use of the data in their publications and not to share the data with others who are not on the ARM Science Team. Permission can be requested to supply data to groups outside the ARM Program for specific projects. In such cases, if permission was given, a conditions form would be produced by ECMWF to be signed by the principal investigator of such a group.
