The first generation of TAHMO stations have now been in the field for 2 years in Senegal, Ghana, Kenya, Uganda, and South Africa. In this entire time we have been working closely with the people in the field as well as the station manufacturer to develop the next level in station performance. The second generation of stations are expected to go to the field in January 2015! A business-card sized solar pane will enough power to report every hour, around the clock, with a back-up battery power sufficient for 3 months, just in case. The station will have internal barometer, a sonic anemometer that can measure low winds also far below the WMO standard, and a rain gauge that has no moving parts and 0.014 mm resolution that is over 10 times better than the WMO guidelines request, and the sonic wind speed sensor resolves down to 0.01 m/s. In June the design will be consolidated to a single compact cylinder.
