VSP data is site specific. The VSP system is an integration of NCEP forecast model data and up-to-date local sensor observations. Both airport (METAR) and Internet-accessible private sensors are supported. The latency, update frequency and effective footprint of VSP data depend on the attributes of the sensor data.
VSS historical data is based on the 35-km resolution NCEP Climate Forecast System Reanalysis (CFSR) state-of-the-atmosphere and derived variable data. Special variables not in the CFSR dataset, such as direct normal irradiance (DNI), apparent temperature and calculated heat content indexes are also offered.
The VSP forecasts have been shown to provide the highest accuracy for the first 24 hours. VSS historical data has been verified with METAR and field-research-sensor data. The SP system provides high-quality environmental input to aid analysis and support a wide range of applications and systems including: energy management and efficiency, renewal energy assessment, climatology research, agriculture, demand planning, site and building modeling, and agriculture. SP data can be a complement to raw sensor observations or an accurate alternative in remote areas where observations are sparse.
The web portal interface will be demonstrated and data quality comparisons will be shared during the presentation.
