Water Stress CWSI Thermal
Find stress 2-3 days early, 25% water save
Mission briefing
Water Stress CWSI Thermal sits in the growth stage of the crop cycle. It runs on a m30t carrying thermal 640 radiometric, and in Bihar the window is v6 maize, pi rice, weekly at a frequency of weekly. Expect roughly 150ha/hr per sortie, and stand the drone down outside the wind <6m/s, clear sky, 11am-3pm envelope — flying past it wastes chemical and risks drift onto neighbouring plots. Readings are interpreted through CWSI = (Tc-Ta), so the payload has to output those bands rather than plain RGB. Find stress 2-3 days early, 25% water save On a medium-difficulty mission like this, the cost driver is not the drone — it is the number of return trips and the pilot hours around them, which is what the payback maths on the economics page turns on.
