Previous case studies have shown that troposheric weather forecasts can be improved by exploiting space-based measurements of the ozone total column. Those studies obtained improved estimates of the PV field by exploiting the space-time dependent correlation between the ozone total column and the partial vertical average of the potential vorticity (PV): the global coverage of the space-based ozone measurements helped to compensate for the gaps in coverage in the ground based and radiosonde networks of meteorological sensors. The improved PV maps were then inverted to derive improved estimates of the wind field. The present work investigates the utility of using ozone profile date to supplement or replace the ozone total column data in such applications, by comparing the tightness of the profile correlation to that of the column correlation.
