Manual on Sea-level Measurements and Interpretation, Volume V: Radar Gauges

Abstract

Volume 5 which is devoted specifically to ‘Radar Tide Gauges’. Radar range finders have been used in industry (where they measure the levels of liquids in tanks) and hydrology (for measuring river, lake and reservoir levels) for many years and, in the decade since Volume 4, have been applied to measuring sea level at many locations. They have already replaced the previous tide gauge technologies in many countries. Their low cost (in most cases) and the fact that they are relatively easy to install and maintain mean that they have been the technology of choice whenever new sites have been instrumented or older ones refurbished. They can be interfaced easily to data loggers and telemetry platforms, such that their data can be displayed almost instantly at centres around in the world. However, many questions remain as to their suitability for sea level monitoring within national and international networks such as GLOSS. At the 13th meeting of the GLOSS Group of Experts in Liverpool in November 2013, a new edition of the Manual was proposed that would focus on this particular technology and problems with its use...
