DYNAMICAL OZONE AND TEMPERATURE CLIMATOLOGY - Data description - This file contains information about the dynamical ozone climatology prepared by the Institute of Environmental Physics, University of Bremen, Germany. This climatology has been summarised and published in L.N. Lamsal, M. Weber, S. Tellmann, and J. P. Burrows, Ozone column classified climatology of ozone and temperature profiles based on ozonesonde and satellite data, J. Geophys. Res., 109, D20304, doi:10.1029/2004JD004680, 2004. It has been a genaral practice to prepare the zonal monthly mean climatology. In recent days, the need of the climatology in terms of some dynamical coordinates has been realised. By using the datasets from ozonesondes, SAGE II, POAM III this climatology has been prepared with total ozone as the additional coordinate. The present climatology is regional, seasonal, and classified by total ozone. Data sources ------------ - Out of 36 ozonesonde stations used in the preparation of this climatology, 6 come from NH polar region, 13 from NH midlatitude region, 12 from tropics, 2 from SH midlatitude region, and 3 from SH polar region. - This climatology is based on the 11 years of ozone observation from 1990 to 2000. Some stations with ozone observaton of less than 11 years are included to increase the geographical coverage. - SAGE II data belongs to the same base period as ozonesondes. But the POAM III data cover the period from 1998 to 2002. - Temperature data come from radiosonde (with ozonesonde), NMC (SAGE II), and UKMO (POAM III) Structure of climatology ------------------------ Regions: Tropical latitude [30S - 30N] , Midlatitude [30 to 60], Polar latitude [60 to 90] Seasons: Winter/Spring [dec, jan, feb, mar, apr, may], Summer/Fall [jun, jul, aug, sep, oct, nov] in NH Winter/Spring [jun, jul, aug, sep, oct, nov] Summer/Fall [dec, jan, feb, mar, apr, may] in SH Ozone class: Class interval of 30 DU, the number of the class differs with regions and seasons. There are basically six different datasets for each case: ozone number density in 1.e+18 molec./m3, ozone volume mixing ratio in ppm and temperature in K. Three for the mean and three for the standard deviation for ozone class of 30 DU as mentioned before. There are 54 ascii files in total. By the name of the file one can guess what really the file contains. For example, iup_doc_shpol_sf_o3vmr_sd.dat Each of the terms separated by underscore has got a meaning as follows. iup : Institute of Environmental Physics doc : Dynamical Ozone Climatology sh : Southern Hemisphere nh : Northern Hemisphere tro : Tropical Region mid : Midlatitude Region pol : Polar Region ws : Winter and Spring Seasons sf : Summer and Fall Seasons o3nd : Ozone Number Density o3vmr : Ozone Volume Mixing Ratio temp : Temperature sd : Standard Deviation dat : Data The files for class standard deviation have the extention 'sd' whereas the files for the class mean do not have. Each of the files has headers for the information of the data. Data are kept in simple format so as to make the software to read the data easier. **************************************************************************** NOTE: * ---- * If parts of this data is used in scientific publications, we kindly ask * you to cite our work as follows: L.N.
