The ARM External Data Center (XDC) at Brookhaven National Laboratory identifies sources and acquires data, called "external data", to augment the data being generated within the program. The external data acquired are usually converted from native format to either netCDF or HDF formats. For information on reading these formats see Reading netCDF, HDF and GRIB Files.
The External Data Center collects and processes a wide variety of data including model, satellite and surface data. For more information on available data streams see XDC data set descriptions.
The XDC also provides database support for ARM. For descriptions and links to these databases, please see ARM Databases Maintained by the XDC
