The ATMOS 31 measures precipitation rate one raindrop at a time using a drip counter for far more precise results. There are no moving parts to clog or come apart, so it will never malfunction, requiring a lot less maintenance work on your part.

If you want accurate wind profiling, a sonic anemometer is the obvious choice. Designed with canopies in mind, the ATMOS 22 registers even the lowest thresholds of wind speed (0 m/s) with the added ability to detect fine-scale variations within 0.01 m/s resolution.
