Q: My data values are much larger than I was expecting. What units are the data in?


Level 1 data are supplied as calibrated at-sensor (ie not atmospherically corrected) radiance in units of uW/cm2/sr/nm (microwatts per centimetre-squared per steradian per nanometre). They are also multiplied by 1000 in the delivered files to avoid problems with floating-point arithmetic and storage.
