AB: Over the last decade there has been a growing awareness across Europe of the possibilities of using microwave links for the measurement of path-averaged precipitation. In the UK our research initially focused on the use of specially chosen dual-frequency links --- we will present a summary of that work, and of the possibilities that it presented for distinguishing between rain and melting snow. We will also reference recent work elsewhere in Europe that has examined the potential use of commercial links. However, our primary focus will be a presentation of the results of two current research endeavours. We will show that microwave links can perform a useful role as a successful substitute for rain gauges in the final stage of adjusting the estimates of rainfall from a weather radar. We will illustrate this with data from an operational UK Met Office radar. Our second current research area has been an investigation of the feasability of determining information about the drop-size distribution from examination of the differential phase of a link, with information transmitted at 45 degrees and with the horizontal and vertical components being separately received.
