Idaho Power Company Lowman Sounding Data [IPC]

Project:

Summary

This dataset contains sounding data from the Idaho Power Company at the Lowman site for Seeded and Natural Orographic Wintertime clouds - the Idaho Experiment (SNOWIE). Idaho Power utilizes Lockheed Martin LMS6 Radiosondes and Ground Systems.  The LMS6 Radiosondes use GPS data to track the radiosonde’s position and height as well as calculating wind speed and direction.  Other meteorological data that are collected is pressure, temperature, and humidity.  These are calculated from a suite of onboard sensors that include a chip thermistor temperature sensor and a LMU6 humidity sensor.  This data is transmitted to the LMS6 Ground System at a frequency between 400.250 and 405.875 MHz. The data are in ASCII files with fixed width columns. The Lowman sounding file names have the prefix "KLOW". Refer to the readme for further information.

Versions
  • 1.0 (2017-11-09)
  • 1.1 (2017-12-20):

    It was found that the file KLOW201702191801.txt was actually a sounding from the Crouch site.  There was a sounding at Lowman at this time and this version now has the correct Lowman sounding for this time.

  • 1.2 (2018-01-08):

    There are two changes in this version.

    The previous version included two files that had the wind speed in knots rather than the expected m/s (KLOW201702191801.txt and KLOW201703041401.txt).  In this version all files now have the wind speed in m/s.  

    The previous version included one file that had the data cut off prior to the end of the sounding.  The file KLOW201703041401 stopped at 500mb.  In this version this sounding now extends to 250mb.

(Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
