Featured Data
The ARM Archive receives data daily. The following data sets and streams may be of interest to you:
- Climate Modeling Best Estimate Product
- 3-hour Temporal Resolution ISCCP Cloud Data Around the ARM sites: ISCCP Cloud ARM Evaluation Data
- Aerosol Best Estimate and Best Estimate Angstrom Exponent and Aerosol Extinction Profiles: ABE ARM Evaluation Data for NSA and SGP
- Direct Aerosol Forcing for NSA, SGP, and TWP: Aerosol Uncertainty PI Product Data
- Aerosol Retrievals from SGP MFRSR data: PI Product Data
- 95 GHz W-Band ARM Cloud Radar (WACR) and MPL observations from the Niamey AMF deployment: WACR-ARSCL PI Product Data
Data collected through the routine operations and scientific field experiments of the Atmospheric Radiation Measurement (ARM) Program and ARM Climate Research Facility (ACRF) are stored and distributed through the ARM Archive. Routine data are collected from instrument measurements and stored in data files for each collection interval (typically hourly). Each data file is named using the ACRF file naming convention. The standard file format for ACRF measurements is NetCDF, a self-describing binary format. The structure of a NetCDF data file for a specific data stream is defined and managed by a data object design (DOD).
The ARM Archive makes these data publicly available from here and from its website. To place a data order, browse instruments, measurements, and data and look for pages that have "add to cart" in their right-side navigation.
A day of data files is bundled or processed into a single 24-hour file that represents a data stream, which is then stored at the ARM Archive.
