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

Abstract: Sparv Embedded, Sweden (http://windsond.com, last access: 22 February 2019), has answered the call for less expensive but accurate reusable radiosondes by producing a reusable sonde primarily intended for boundary-layer observations collection: 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 th… Show more

“…They were both launched in-situ and at the same time to compare accuracy. 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.…”

“…reaching up to the tropopause) with 6-hour intervals, the first one was launched at 1800 UTC on D-1 and the last one at 1200 UTC on D. In addition, frequent radiosondes (FRS) were launched up to an altitude of 650 m AGL at 0300 UTC, 0600 UTC and 0900 UTC. At 0600 UTC, 2 FRS were launched simultaneously with NRS to evaluate the performances of the FRS 16 . An excess of radiosondes led to the decision to increase the number of NRS toward the end of the campaign.…”

“…To meet the needed student funding, around 70% of the total project budget of $15,000 (obtained through a University Corporation for Atmospheric Research (UCAR) COMET Outreach National Weather Service Partners program grant) went to paying UG student stipends. The remaining funds went to support low-cost variety instrumentation and sensors, including 21 HOBO MX2302A temperature (accuracy +/-0.2 °C) and humidity (accuracy +/-2.5%) sensors and a lightweight (Windsond.com) rawinsonde system (Bessardon et al 2019). Despite their low cost, these sensors have been accurate, dependable, relatively easy to setup, and provide all of the data needed to achieve the overarching scientific goals.…”
