Short Summary

This paper introduces the Soil Moisture Operational Product System (SMOPS), a one-stop shop for microwave satellite soil moisture observations, and highlights its key features and developments. SMOPS offers high-quality products, comparable to those of the SMAP mission.

Objective

• To provide a comprehensive overview of the major characteristics and features of SMOPS datasets

Study Configuration

• Spatial Scale: Global (with focus on 25 km resolution)
• Temporal Scale: Near real-time (NRT) and climate data record (CDR)

Methodology and Data

• Models used:
  • Machine learning models for downscaling and blending
  • Satellite observations from various sensors
• Data sources:
  • Microwave satellite soil moisture retrievals
  • SMAP product as a benchmark

Main Results

• High-quality SMOPS products comparable to those of the SMAP mission
• Satisfactory consistency between SMOPShr and SMOPScdr
• SMOPShr provides more detailed spatial information than SMOPScdr

Contributions

• Development of a one-stop shop for microwave satellite soil moisture observations (SMOPS)
• Introduction of machine learning models for downscaling and blending
• Provision of high-quality products comparable to those of the SMAP mission
