EERL performs research in the field, mainly in the Arctic and Antarctic. The team has developed a tethered balloon system with a payload that measures meteorological, aerosol and cloud variables. To make the system as lightweight as possible a few instruments have been replaced by smaller and lighter versions. To ensure consistency between observations the old and new instruments need to be compared.
This project includes the inter-comparison of already obtained data sets from wind sensors (the SmartTether – old and a sonic anemometer – new). The task is to determine whether the instruments show the same values and whether there are corrections to be done. Also the new sonic data processing routine can be coded. The other pair of instruments to be compared are cloud droplet spectrometers (the miniCDA – old and LOAC-new). In order to compare them, a set up in a climate chamber at ALPOLE needs to be build to generate a cloud. The droplets will then be measured under controlled conditions and the data sets compared. This requires some creativity to build the set up.
This work will be supported by EERL’s technician Lionel Favre and a PhD student and postdoc.
