Monthly Climate Normals for Gifford Pinchot National Forest: A 1991 to 2020 Data Profile

Name: Gifford Pinchot National Forest monthly climate normals
Creator: NASA POWER

Review established climate patterns at a representative coordinate within Gifford Pinchot National Forest. This dataset provides monthly averages for temperature, daily precipitation, relative humidity, wind speed, and daylight hours derived from NASA POWER measurements covering the 1991 to 2020 period. These records establish long-term baseline atmospheric conditions rather than current weather or forecasts for the entire landscape.
