# Description:
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 (https://github.com/overeem11/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. These papers use data from NEC (0.1 dB resolution) and Nokia (1 dB resolution) CMLs or only Nokia CMLs. The open dataset contains solely data from Nokia CMLs. A manuscript which will describe the exact characteristics of this dataset is in preparation. Details on the data format (Appendix A) and the processing of data to retrieve rainfall employing RAINLINK can be found in: Overeem, A., Leijnse, H., and Uijlenhoet, R.: Retrieval algorithm for rainfall mapping from microwave links in a cellular communication network, Atmos. Meas. Tech., 9, 2425–2444, https://doi.org/10.5194/amt-9-2425-2016, 2016. The data have been provided by the mobile network operator T-Mobile NL. Note that the transmitted signal levels, which were not available and are thus not provided, may be considered constant for each individual link.



# Data files:
- "CMLs_20120530_20120901.dat": each row provides the data from one individual microwave link and 15-min time interval. Data from 30 May up to and including 1 September 2012.
- "CMLs_20110609_20110911_21days.dat": each row provides the data from one individual microwave link and 15-min time interval. Data from 21 days in the period 9 June up to and including 11 September 2011.



# Explanation of data fields:

Frequency 
Microwave frequency f (GHz).

DateTime 
Date and end time of observation (YYYYMMDDhhmm, i.e. year (2011), month (09), day (11), hour (08), minutes (00): 201109110800). Time zone is UTC.

Pmin 
Minimum received power (dBm).

Pmax 
Maximum received power (dBm).

PathLength 
Length of microwave link path L (km).

XStart 
Longitude of start of links (degrees); WGS84.

YStart 
Latitude of start of links (degrees); WGS84.

XEnd 
Longitude of end of links (degrees); WGS84.

YEnd 
Latitude of end of links (degrees); WGS84.

ID
Link identifier (a number). For the same link the same ID is used troughout the entire 2011 and 2012 dataset.
