Operational activities for climate monitoring
The USRCC monitors the current state of ocean-land-atmosphere system by using different variables, such as Sea Surface Temperatures (SST),
2m air temperature, precipitation and wind, over the WMO Regional Association IV and the sub-region on the Caribbean, Central America and Mexico.
These parameters are derived from several sources:
The USRCC provides access to these real-time regionalized climate monitoring products that constitute a valuable source of information
to support effective decision-making process and form a basis for operational long-range forecasting and climate research.
- data assimilation systems: Climate Data Assimilation System (CDAS) analysis, CPC unified gauge analysis and Optimum Interpolation (OI) analysis
- observing stations and reports: Global Telecommunication System (GTS) station reports
- satellite estimates: CPC Morphing Technique (CMORPH) estimates and infrared satellite images.
