Global GNSS Co-Located Meteorological Data at 15-Minute Resolution

15-minute meteorological data files contain temperature, pressure, and humidity readings from instruments co-located with GNSS ground receivers. The dataset is maintained by NASA's Crustal Dynamics Data Information System (CDDIS) and includes data from multiple global satellite systems since 2011.

Use Cases

• Analyze temperature variations and their correlation with GNSS signal quality using the 15-minute temperature readings.
• Model atmospheric pressure for weather forecasting and climate research using the sub-hourly pressure data.
• Study humidity patterns near GNSS stations to assess local environmental impacts on measurement accuracy.
• Integrate meteorological parameters like temperature and pressure with GNSS positioning data for enhanced geospatial analysis.

Strengths

• Data is collected from a global permanent network of ground-based receivers.
• Includes meteorological data from multiple GNSS systems (GPS, GLONASS, Galileo, etc.) since 2011.

Limitations

• Specific row count, file size, and geographic distribution details are unknown.
• The data format (RINEX) requires specialized parsing tools for analysis.
