NMC Global Daily Stratospheric Analyses from TOVS

These global analyses were prepared daily at 12Z to support NMC's monitoring of temperature trends in the stratosphere. The analysis system used satellite temperatures from the TIROS Operational Vertical Sounder (TOVS). Global coverage is achieved by combining the 65 by 65 polar stereographic grids for each hemisphere, north and south. The analyses are available on 8 mandatory levels from 70 mbar to 0.4 mbar, and include pressure, geopotential height, temperature, and total column ozone.
