Eighth Symposium on Integrated Observing and Assimilation Systems for Atmosphere, Oceans, and Land Surface


Developing a Technique for Verifying Radiosonde Solar Radiation Correction Algorithms (formerly paper 3.5)

James Fitzgibbon, NOAA/NWS, Silver Spring, MD; and J. Facundo

The NWS has developed a technique for verifying the algorithm used with radiosondes for applying solar radiation corrections to temperature measurements. Both solar and infra-red corrections are applied to temperature measurements, but the solar correction has the greatest effect, especially in the stratosphere. However, the algorithm within either government-furnished or vendor-furnished software must be validated to ensure the corrections are being applied properly as a function of time of day, latitude, and solar angle. This paper delineates the technique used by the NWS to validate the solar radiation correction for the new brand of 1680 MHz GPS radiosondes NWS intends to use in its network beginning in 2003. Preliminary results from use of this technique will also be discussed
