Total ozone content in the atmosphere
Microtops In 2008 the National Institute of Geophysics, Geodesy and Geography began regular measurements of total ozone content in the atmosphere over the territory of Bulgaria. Measurements shall be made daily when weather conditions allow with a solar photometer, manufactured by Solar Light Company, USA, 2006., http://www.solarlight.com. Data on days when no measurement is possible, complete with satellite measurements from the Ozone Monitoring Instrument (OMI), which are available at http://ozoneaq.gsfc.nasa.gov/. OMI
Total ozone

Course of monthly averages of total ozone from 1996 to 2015. Measured in NIGGG values are combined with data from other satellite equipment.
The total amount of ozone over Bulgaria shows a steady upward trend.

Course of daily values of total ozone over the past 12 months. Green color shows the averages for the period 1996-2007, the measurements obtained by satellite. Blue shows the average values for a particular month.

FORECAST OF 31-DAY RUNNING MEAN
OF TOTAL OZONE OVER BULGARIA


The forecast of adjusted values of total ozone over Bulgaria was made under developed in NIGGG section "Atmospheric Physics". The local model is based on statistically justified dependencies of the season, the stratospheric temperature and the quasibienal equatorial oscillation of the stratospheric zonal wind. In red are shown adjusted values of measurements and in blue - forecast three months ahead.
