SWEX: JSU Mobile Surface Meteorology: Automobile

Summary

Surface meteorology parameters measured by sensors mounted to an automobile which was driven on roads within the SWEX (Sundowner Winds Experiment) field project domain and surrounding region from 4 April to 13 May 2022.

Archive note

This dataset includes the observations collected during IOP/EOP operations. There is a companion dataset that has observations from non-IOP/EOP days.

Data Quality	final
Versions	0.1 (2023-01-05) 1.0 (2025-02-27): The two new columns are for the 'corrected elevation' and a calculated relative humidity using temperature from the fast response temperature sensor. 1.1 (2026-06-01): The data files were originally in 7z compressed archive files. This version just extracts the individual CSV files. The data itself is unchanged. (Only the current version of the data is available to order.
