Space Physics Data from NASA Missions via CDAWeb

NASA's Space Physics Data Facility archives data from numerous space missions, including ACE, Cluster, GOES, OMNI, and Voyager. The CDAWeb system provides browsing and listings for this archived data in CDF and netCDF formats. This collection covers both recent and historical missions for heliospheric science.

Use Cases

• Analyze time-series data from the OMNI mission to study solar wind parameters and magnetospheric conditions.
• Correlate particle and field measurements from the Van Allen Probes with data from the GOES satellites for space weather research.
• Compare plasma data from the older IMP-8 mission with newer measurements from the Wind spacecraft to study long-term heliospheric trends.
• Use CDF and netCDF formatted data from the ACE and STEREO missions for multi-point analysis of coronal mass ejections.

Strengths

• Archived by NASA's Goddard Space Flight Center, an authoritative source for space physics data.
• Covers a wide range of missions, including over 20 recent ones like ACE, Cluster, and THEMIS, plus older missions like IMP-8.
• Data is provided in standard scientific formats (CDF and netCDF) suitable for analysis.

Limitations

• The primary access point is an HTML web service (CDAWeb), which may not be optimized for bulk or programmatic data retrieval.
• Specific data volumes, row counts, and column structures for individual mission datasets are not provided in the metadata.
• The license is unspecified, which may create uncertainty for commercial or redistribution use cases.
