QUARC - Quantifying Uncertainty in Adjusted Radiosonde Climate records

QUARC is an automatic radiosonde homogenisation system that has been used to produce ensembles of radiosonde temperature datasets. It uses a neighbour based, iterative approach similar to the manual method employed in HadAT (the Hadley Centre gridded radiosonde temperature product). Each dataset realisation has been created by using a different set of system parameter settings to within reasonable bounds. These system settings reflect different plausible assumptions that could be made in the development of a climate quality radiosonde dataset. The results can be used to investigate uncertainties in long term radiosonde temperatures.

Brief description of the data

This website contains summary files for the experiments used within the paper (see references below). These summaries include long term trends that were estimated from each experiment. They are currently only available for a subset of the experiments carried out and only through a password protected area. Please contact us if you require access to these data.
