UV Index: Monthly
Means and Maximums - The monthly mean and maximum UV Indices for the 58 US
forecast cities in the form of a map.
Ozone Hole Weekly
Update - NOAA monitors the progression of the ozone hole from space and on
the ground in Antarctica. The current year's ozone hole plot shows the
progression of this year's ozone hole and is placed in reference with 1998's record
setting ozone hole conditions and conditions over the previous nine years.
Meteorological Conditions and Ozone In the Polar Stratosphere -
NOAA monitors the meteorological conditions and ozone amounts in the
stratosphere. The Climate Prediction Center (CPC) presents graphics from this monitoring
effort to aid in visualizing the evolution of the South Polar "ozone
hole" and factors important for ozone depletion in the polar areas.
Information on the size of the polar vortex and the ozone hole, the area in which
air cold enough to form Polar Stratospheric Clouds (PSCs) and which parts of this cold air are sunlit
such that photo-chemical ozone depletion processes can occur. In
addition, zonal profiles show the thermal evolution in the polar area.
Analyses Times Series - The CPC global temperature analyses are derived each day
at 8 stratospheric levels. Graphical aids for monitoring temperature anomalies in the
stratosphere are shown along with daily temperature values averaged over each latitude
region. The values for the current year may be compared to the average values for each day and the extreme maximum and
minimum values for the entire temperature analysis record from 1979 to current.
SBUV-2 Total Ozone -
Daily total column ozone maps are made operationally from data obtained from the Solar
Backscatter Ultraviolet (SBUV/2) instrument onboard the NOAA-14 satellite.
TOVS Total Ozone -
NOAA's TIROS Operational Vertical Sounder(TOVS) is a suite of three instruments: the
Microwave Sounding Unit(MSU), the High resolution Infrared Radiation Sounder(HIRS), and
the Stratospheric Sounding Unit(SSU). Each instrument measures radiation emitted by the
Earth at several different wavelengths. The data gathered is presented in a map.
SMOBA (Stratospheric Monitoring Ozone
Blended Analysis) - This analysis has applications for the input to
CERES/EOS heating rate calculation and the initial conditions for numerical ozone
Temperature Analyses 6-day Archive - The CPC produces GRIB data files and
stereographic maps of the 50mb temperatures for the northern and southern polar areas.
