Bayesian retrieval of water vapour column

This week I've been in part working on Bayesian retrieval of water vapour column from prototype WVR data.

The attached plot shows a typical result: It shows the retrieved *zenith* water vapour column as a function of time while the telescope was tracking a source for about an hour (it was setting at the time). The colour scale represents the posterior distribution and is hence an indication of the confidence in the retrieved values.

You can find out more detail on the retrieval method in my most recent talk at these web pages:
