Shown here are: (top) INTERPOLATEDSONDE temperature output profiles for July 1, 2015, through July 5, 2015, at the Southern Great Plains (SGP), and (bottom) INTERPOLATEDSONDE relative humidity output profiles for July 1, 2015, through July 5, 2015, at SGP.

Atmospheric Radiation Measurement (ARM) Climate Research Facility radiosonde (SONDE) files provide a key reference to the atmospheric state, but this is only available at the time of those radiosonde launches. However, many applications or retrievals may require a quick estimate of the atmospheric state at higher time resolution, or may simply demand a more convenient time-height gridding of these SONDE data. The Interpolated Sounding (INTERPSONDE) value-added products (VAPs) transform ARM radiosonde (SONDE) data into continuous daily files with thermodynamic parameters on fixed time-height grids. INTERPSONDE linearly interpolates the atmospheric state variables from available SONDE datasets in time for each height level.

There are various benefits to the separate SONDE files and radiosonde VAPs. The INTERPSONDE VAP faithfully reports the same thermodynamic profile at the time of the ARM radiosonde launch. By excluding model outputs, INTERPSONDE products are typically available for download faster than ARM’s Merged sounding (MERGESONDE) VAP, and these thermodynamic profiles are independent of model influence as in MERGESONDE. For sites with frequent radiosonde launches, INTERPSONDE may more directly facilitate model evaluation with radiosonde observations. Because of this short turnaround period for product generation, the INTERPSONDE VAP is currently used by several routine ARM retrieval products such as the ARSCL and MICROBASE suites of cloud property VAPs.

This VAP provides one-minute time resolution. For additional information on the VAP interpolation procedures, please consult the technical report for the product.
