Combined vertical ozone profile databaseBodeker Scientific produces a 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. A publication describing the construction of this database is currently in preparation.The raw individual ozone data are sourced from the BDBP database (see The BDBP).
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.: **Tier 1.1 (Anthropogenic):**This comprises the mean annual cycle plus contributions from the EESC and linear trend basis functions.**Tier 1.2 (Natural):**This comprises the mean annual cycle plus contributions from the QBO, solar cycle and El Niño basis functions.**Tier 1.3 (Natural & volcanoes):**Tier 1.2 but now also including contributions from volcano basis functions.**Tier 1.4 (All):**Constructed by summing the contributions from all basis functions.
1.1.0.6 of the BDBP is available from here. To access the data you will need a username and password. These can be obtained by emailing datasets@bodekerscientific.com. If you would like to be informed of updates to this database, please email me at greg@bodekerscientific.com and I will add you to my list.You can also access this database via the British Atmospheric Data Centre (BADC) here. There are 20 files available named CCMVal2_REF-B1_BSOzone-XX-YYY_TierZZ_T2Mz_O3.nc where: - CCMVal2 indicates that these data files have been formatted to allow easy use in the CCMVal2 project.
- REF-B1 indicates that the time period covered is similar to that for the REF-B1 simulations.
- XX is either 'MR' for mixing ratio or 'ND' for number density.
- YYY is either 'PRS' to denote that the data are on pressure levels or 'ALT' to denote that the data are on altitude levels.
- ZZ denotes the Tier: '0', '1_1', '1_2', '1_3' or '1_4'.
- T2Mz denotes that these are monthly means in two dimensions (latitude and altitude/pressure).
At present Bodeker Scientific has no financial support to maintain this database and so if there is anyway that you can contribute towards the maintenance of this database, that would be much appreciated. That said, this database is made freely available to any not-for-profit organisation or individual. If you are going to be using this database in a publication, please let me know. At the very least please include the following acknowledgement: We would like to thank Greg Bodeker (Bodeker Scientific) and Birgit Hassler (NOAA) for providing the combined vertical ozone profile database. |
