Data Quality
Member DW1373 of the Citizen Weather Observer Program (CWOP).
The positioning and calibration of the weather station sensors has been carefully considered to maximize accuracy of the readings. We use CWOP to help make sure our data is accurate.
The following is data reported to CWOP for Gigharborweather.com (DW1373 in blue) with the predicted data based on surrounding stations (Analysis in red). Also included is the reported data for the National Weather Service meteorological station at Tacoma Narrows Airport (KTIW in purple). Tacoma Narrows Airport is the weather most often quoted by news and Internet sources for the Gig Harbor area. It is a mere 5.6 miles from Gigharborweather.com.

CWOP is a private-public partnership with the National Oceanic & Atmospheric Administration. It's three main goals:
1) To collect weather data contributed by citizens.
2) To make this data available for weather services.
3) To provide feedback to the data contributors so that they have the tools to check and improve their data quality.
