I see on a number of flights that have only short periods of some measurements such as winds and temperature. All parameters should always have values; however, when a measurement is not reliable, the missing value codes (MVCs) is the value. MVCs can result because a necessary measurements needed to calculate the parameter is not available (contains MVCs) or manual edits have been applied to place MVCs in… text/html 2020-01-29T17:25:48+00:00 Anonymous (anonymous@undisclosed.example.com) https://atmoswiki.azurewebsites.net/doku.php?id=atmos:citation:high_volume_particle_spectrometer_hvps&rev=1580318748&do=diff High Volume Particle Spectrometer (HVPS) Manufacturer: Stratton Park Engineering Company Inc.
