Twelve month analysis of atmospheric averages based on a representative coordinate in California.

Lassen National Forest Monthly Climate Normals: Temperature, Precipitation, and Wind Patterns

Name: Lassen National Forest monthly climate normals
Creator: NASA POWER

Analyze the long term climate record for Lassen National Forest through monthly temperature averages, precipitation rates, relative humidity, wind speed, and daylight duration. These measurements provide a consistent baseline for understanding the annual atmospheric cycle between 1991 and 2020 at a fixed point of 1700 meters elevation. This data focuses on stationary historical trends rather than current weather fluctuations or seasonal forecasts.
