INCOMPASS: Radiosonde measurements from the Indian Institute of Technology (IIT) airstrip, Kanpur, India
Abstract
This dataset contains temperature, humidity, wind and GPS location information recorded from 137 radiosondes launched during July 2016 as part of the NERC/MoES Interaction of Convective Organization and Monsoon Precipitation, Atmosphere, Surface and Sea (INCOMPASS) field campaign. All radiosondes were launched from the airstrip of Indian Institute of Technology (IIT) Kanpur, Uttar Pradesh, northern India, from the location 26.519N, 80.233E, 126m above sea level. Launches took place between 5th July and 28th July at 00, 06, 12, 18UTC. The Vaisala RS41-SG radiosondes were fitted to Totex TA350 balloons.
The data were collected as part of the INCOMPASS field campaign May-July 2016, funded by Natural Environmental Research Council (NERC) (NE/L01386X/1). The aim of the project was to improve the skill of rainfall prediction in operational weather and climate models by way of better understanding and representation of interactions between the land surface, boundary layer, convection, the large-scale environment and monsoon variability on a range of scales.

| Data lineage: |
The Vaisala MW41 DigiCora sounding station receives radiosonde measurements via telemetry and stores them in a packaged (zipped) format consisting of XML files. Only the "SynchronizedSoundingData.xml" file has been used (one for each launch), and converted to Netcdf (by AG Turner during September 2018) using a program running in IDL8.5. The data were then sent to the Centre for Environmental Data Analysis (CEDA) for archiving. |
| Data Quality: |
Known errors: INCOMPASS-UoR-Vaisala-MW41-RS41_IITKanpur_2016071806a.nc contains no usable ascent data. A replacement launch was made soon after, "…2016071806b.nc". INCOMPASS-UoR-Vaisala-MW41-RS41_IITKanpur_2016071506.nc appears to have an underfilled or leaking balloon, since there are several periods of ascent/descent within the profile.
