The default colors, fonts, and such in MATLAB plots make them easy to spot on the web:

Bright sunlight can interfere with the Sharp sensor. The range sensor voltage and it’s deviation increase when the photodiode reports > 50+ mV. Since it usually doesn’t snow when the sun is out, one approach is not to make measurements in bright sunlight. If you want to watch the snow melt and compact in the sun light, the data can be corrected using a cubic polynomal and a moving average. Accuracy in the lower light range can be improved by using interpolation.
