PI Product : Atmospheric State, Cloud Microphysics & Radiative Flux

[ ARM Principal Investigator (PI) Data Product ]

Atmospheric thermodynamics, cloud properties, radiative fluxes and radiative heating rates for the ARM Southern Great Plains (SGP) site. The data represent a characterization of the physical state of the atmospheric column compiled on a five-minute temporal and 90m vertical grid. Sources for this information include raw measurements, cloud property and radiative retrievals, retrievals and derived variables from other third-party sources, and radiative calculations using the derived quantities.

Purpose

Data were collected in order to help and improve the climate and earth system models.

Attribute Accuracy No formal attribute accuracy tests were conducted
Positional Accuracy No formal positional accuracy tests were conducted
Data Consistency and Completeness Data set is considered complete for the information presented, as described in the abstract.Users are advised to read the rest of the metadata record carefully for addtional details.
Factor Affecting the Research The data cannot be used when either the MWR or MMCR are wet from dew or precipitation or when reflectivity or velocity measurements suggest the profile is dominated by precipitation.
Access Restriction No access constraints are associated with this data.
Use Restriction No use constraints are associated with this data.
