Description

This data set contains meteorological measurement data collected during the Field Experiment on Sub-mesoscale Spatio-Temporal variability at Hamburg (FESST@HH) between June and August 2020. The observational set up of FESST@HH consisted of a ground-based network of 103 autonomous measurement stations (see photos), that covered the greater area (50 km x 35 km) of Hamburg (Germany; 53.5 °N 10.0 °E) with the primary goal to observe the spatial dimension of convective cold pools. During the experiment 82 low-cost and self-designed APOLLO (Autonomous cold POoL LOgger) stations sampled air temperature and pressure at 1-s resolution, while 21 WXT weather stations with commercial sensors provided additional information on relative humidity, wind speed and precipitation at 10-s resolution. All variables are sampled at a height of 3 m above ground, if not indicated otherwise.

The data are sorted on a daily basis in folders according to the measuring station. In addition, photos of all stations are available.

With the dense network of more than a hundred stations, which have been set up on the private property of many volunteers, the team from the Meteorological Institute has for the first time succeeded in recording the life cycle of cold pools under thunderstorms in space and time, as well as many other phenomena: the urban heat island, Baltic Sea fronts, floor winds and gravity waves.

Last update of data set at ICDC: May 2022
