DC3: NSSL Oklahoma Mobile Mesonet Meteorological Data


This dataset contains NSSL Oklahoma Mobile Mesonet Meteorological data obtained during the Deep Convective Clouds and Chemistry Project (DC3) from 19 May 2012 to 21 June 2012. Data were obtained from two platforms (each equipped with mobile mesonet instrumentation): the NSSL3 in-storm sounding vehicle (denoted "probe 3" or "P3") and the NSSL4 mobile environmental sounding vehicle denoted ("probe 4" or "P4"). This dataset only contains data for Probe 3 and Probe 4. The data are in ASCII format. The filename prefix ends in P3 (e.g. C18095P3) for data files associated with Probe 3, or P4 (e.g. C18096P4) for data files associated with Probe 4. These data files are provided by IOP relative to UTC time and date of departure for the IOP (UTC time relative to 0000 UTC on date of departure). The date and time are indicated in the filenames.

In each file the file header includes a list of variable names in each data record. The nominal data spacing is 1 Hz. There may be occasional missing 1 Hz records, due to QC removal of occasional records that were corrupted in the GPS location group, the time group, the raw observation, or the derived variable groups (which in turn was caused by the different system clocks occasionally getting out of synchronization). The latter removed records are infrequent. The individual sensors on the NSSL mobile mesonet systems were pre-calibrated by the Oklahoma Climate Survey (OCS) instrumentation laboratory prior to the DC3 field phase.
