2011 Precipitation

Top | Table | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec | Yearly

The precipitation is collected in a bucket. As the bucket gets heavier, a set of gears turns indicating the precipitation. Every 15 minutes, the paper tape is punched indicating the current weight of the bucket (measured in inches of precipitation). The tape is manually read from midnight to midnight each day. Accuracy is to the nearest 0.1 (tenth) of an inch.
