Short Summary

This paper focuses on the preliminary performance evaluation and verification of GNSS-R data products derived from the 22-satellite Tianmu-1 constellation, comparing retrieval results from BeiDou, GPS, GLONASS, and Galileo signals against multisource data.

Objective

• To conduct a preliminary performance evaluation and verification of GNSS-R data products obtained from the 22-satellite Tianmu-1 constellation.
• To compare the retrieval results from BeiDou, GPS, GLONASS, and Galileo signals with multisource data to assess their performance.

Study Configuration

• Spatial Scale: Global (implied by satellite constellation and multiple GNSS systems).
• Temporal Scale: Not explicitly stated in the provided text snippet.

Methodology and Data

• Models used: Not explicitly stated in the provided text snippet, but involves processing of GNSS-R signals.
• Data sources: GNSS-R data products from the Tianmu-1 constellation (utilizing BeiDou, GPS, GLONASS, and Galileo signals), and unspecified "Multisource Data" for comparison.
