Why Measuring Rainfall Matters

Gardening, Growing & Food Production

  • Avoid overwatering and shallow root systems
  • Reduce soil erosion and compaction
  • Improve consistency and yields over time

Citizen Science & Community Value

  • Improve understanding of storm impacts

How to Measure Rainfall with the Stratus® Professional Precision Rain Gauge

  1. Choose the right location. Open area away from buildings, trees, and fences. Avoid roof drip lines and sprinkler spray.
  2. Mount securely. The Quick Connect bracket allows easy removal for reading and cleaning.
  3. Read rainfall. Read from the inner measuring tube for precise totals. If rainfall exceeds tube capacity, pour from the outer cylinder in stages and add totals.
  4. Measure snow & ice. Remove funnel and inner tube, allow frozen precipitation to collect in outer cylinder, bring indoors to melt, then measure liquid equivalent.
  5. Empty, reset & prepare. Empty after reading, rinse periodically, reinstall promptly.
