Dataset
Bodeker Scientific vertical ozone profile - Number Density
Abstract
Bodeker Scientific produced a global combined monthly mean vertical ozone profile database spanning the period 1979 to 2007. The database is completely filled such that there are no missing data. This database is used for assessing or constraining global climate model simulations. These data held at CEDA are a copy from Bodeker Scientific taken on November 2012.

Process overview
Title | Computation process: Bodeker Scientific vertical ozone profile |
Abstract | Monthly means are calculated from individual ozone measurements extracted from the The Binary Data Base of Profiles (BDBP), several different satellite-instruments and ozonesondes were used. These are referred to as Tier 0 data. A regression model is fitted to the Tier 0 data at each of 70 pressure/altitude levels. The regression model is of the form: Ozone(t,lat) = A(t,lat) + Offset and seasonal cycle Regression model fit coefficients are expanded in Fourier series to account for seasonality and in Legendre polynomials in latitude to account for meridional structure in the fit coefficients. Regression model output is then used to produce 4 gap free Tier 1 data sets, viz.: |
