Evaluation of Windsond S1H2 performance in Kumasi during the 2016 DACCIWA field campaign

Abstract

Abstract. Sparv Embedded, Sweden (http://windsond.com) has answered the call for less expensive but accurate reusable radiosondes by producing the Windsond S1H2. To evaluate the performance of the S1H2, in-flight comparisons between the Vaisala RS41-SG and Windsond S1H2 were performed during the Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) project (FP7/2007–2013) ground campaign at the Kumasi Agromet supersite (6°40′45.76″ N, 1°33′36.50″ W) inside the Kwame Nkrumah University of Science and Technology (KNUST), Ghana campus. The results suggest a good correlation between the RS41-SG and S1H2 data, the main difference lying in the GPS signal processing and the humidity response time at a cloud top. Reproducibility tests show that there is no major performance degradation arising from S1H2 sonde re-use.

Pyroconvection Classification Based on Atmospheric Vertical Profiling Correlation With Extreme Fire Spread Observations

“…A satisfactory agreement between the temperature ( T s ), dew point temperature ( T d ), and wind bars (speed and direction) was observed on both sonde's profiles projected on a skew‐ T chart (Figure 3), coinciding with a similar experiment by Bessardon et al. (2019). The same layering was observed in terms of thermal inversion and wind shear, including the unstable ABL from surface to 910 hPa and the 3 K inversion and wind shear around 900 hPa.…”
