Daily Meteorological Measurements from Global GNSS Ground Stations

Meteorological data including temperature, pressure, and humidity is collected daily from a global network of ground-based stations co-located with GLONASS satellite receivers. The data is provided in daily 24-hour RINEX format files, one per site, by NASA's Crustal Dynamics Data Information System (CDDIS). The dataset supports atmospheric and positioning research using the Russian GLONASS system, which is similar to the U.S. GPS.

Use Cases

• Analyze correlations between atmospheric pressure and humidity measurements from co-located ground stations to model tropospheric delay for GNSS signal correction.
• Study global temperature trends using daily temperature records from the permanent ground-based receiver network.
• Validate weather model outputs by comparing predicted meteorological parameters against the observed temperature, pressure, and humidity data from specific station sites.

Strengths

• Data is collected from a global permanent network of ground-based receivers, ensuring wide spatial coverage.
• Daily files provide consistent temporal resolution for time-series analysis of meteorological variables.

Limitations

• Specific row counts, column details, and precise geographic coverage for the network are not provided.
• The data format (RINEX) is specialized and may require specific tools or libraries for parsing and analysis.
