Dataset of commercial microwave link (CML) data, which can be used to estimate path-average rainfall between telephone towers. Contains microwave frequency, end date & time of reading, minimum & maximum received power, path length, coordinates, and link identifier. For a network of on average ~2500 links covering the Netherlands having a temporal resolution of 15 min. The dataset, which consists of two files, can be used with the open-source R package RAINLINK ( to estimate path-averaged rainfall and to make rainfall maps. Data have been used in the mentioned papers under "link to publication", but these use either a subset of the dataset or also other data.

Be aware that part of the CML dataset has an erroneous time stamp. It only concerns the data from the year 2012 in file "CMLs_20120530_20120901.dat". The data from "CMLs_20110609_20110911_21days.dat" from the year 2011 are not affected. The time stamp from all intervals from 00:15 through 08:00 UTC is wrong. The corresponding date should be one day later, i.e., 24 hours later. This implies that 33.3% of the ~3-month dataset from 2012 has the wrong time stamp.

This has been corrected in version 2 of the dataset.
