Global Monthly Land Temperature Records From 25,000 Stations

Over 25,000 stations globally provide monthly mean temperature data, both raw and bias-corrected. This beta release from NOAA NCEI is the core dataset for climate monitoring and assessment, with a planned operational release in early 2018. It introduces consistency with daily temperature observations.

Use Cases

• Analyze long-term temperature trends using the monthly mean temperature field from global stations.
• Compare raw and bias-corrected monthly mean temperature columns to assess data adjustment methods.
• Integrate station location data with monthly temperature records for spatial climate anomaly mapping.
• Use the dataset's temporal coverage to calibrate or validate gridded climate model outputs.
• Assess data consistency between this monthly dataset and daily temperature observations as noted in the description.

Strengths

• Contains data from over 25,000 land-based stations globally.
• Provides both raw and bias-corrected versions of monthly mean temperature.

Limitations

• Only monthly mean temperature is available in this beta version; maximum and minimum temperatures are not yet included.
• Labeled as a beta release, indicating potential instability or changes before the operational version.
