Description

This data set contains meteorological network observations collected during the Field Experiment on Sub-mesoscale Spatio-Temporal Variability in Lindenberg (FESSTVaL) from May to August 2021. The observational set up consisted of a ground-based network of 99 autonomous measurement stations that covered an circular area of 30 km in diameter centered around the Meteorological Observatory Lindenberg (eastern Germany; 52.16°N, 14.12°E). The primary goal of the network measurements was to observe the spatial structure of convective cold pools at sub-mesoscale resolution (100 m - 10 km). During the experiment, 82 low-cost and custom-designed APOLLO (Autonomous cold POoL LOgger) stations sampled air temperature and pressure at 1-s resolution, while 21 WXT weather stations based on commercial sensors provided additional information on relative humidity, wind speed and precipitation at 10-s resolution. The data of all network stations is stored in daily files separated after station type and measurement variable.

Limitations: Absolute accuracy of temperature (pressure) generally better than +/- 0.5 K (1 hPa), however, the instrument design focused on the relative accuracy of measurements. The overall data availability of temperature measurements for APOLLO (WXT) stations is 92.0 % (98.1 %). Maintenance logbook and site picutures are attached for further interpretation of measurements.
