Motivated by "Citizen Science" advocate Forest Mimms' and his studies of the atmosphere, I decided to run an initial experiment of water evaporation (or perhaps sublimation) during the New England winter.
Method:
1. Place 500 ml of room temperature water in a plastic pan
2. The pan is 10" x 6" = 0.03876 meters squared surface area
3. Record the initial weight of water and pan in grams
4. Place the pan in a standard location, shielded from wind, at 6:30 am daily (when I leave for work :)
5. Expose to the atmosphere for 24 hours
6. Record the final weight of water and pan in grams, obtain grams water evaporated
7. Quantify daily observation as grams water / meters squared / hour
8. Do no record results for days with measurable precipitation
Results:
Graphed above. Note that pan size and observation time of 24 hours essentially cancels unites such that grams water evaporation is almost identical to g / m2 / h
Future Plans:
1. Continue observations
2. Add morning dew point, ambient temperature, and presence / absence of ice
