 ==== Doppler Lidar ====
 The [[instruments:wind_lidar|Doppler Lidar]] sends out pulses of light in the near-infrared part of the spectrum. The Doppler shift of the signal backscattered by aerosol can be used to infer line-of-sight wind speed within the boundary layer. Scanning in elevation and azimuth allows derivation of the full wind vector. For background information see the [[http://wiki.eg-climet.org/index.php?title=Doppler_Wind_Lidar|EG-CLIMET wiki]].
+==== Meteorological tower ====
+Forschungszentrum Jülich operates as 120 m high [[instruments:tower:tower|meteorological tower]] with platforms for measuring wind, humidity and temperature.

 ==== MRR =====
 The [[instruments:mrr:mrr|Micro Rain Radar (MRR)]] is a vertically pointing FMCW Doppler radar operating in the K-band. From the Doppler spectra the radar reflectivity factor (Ze) and the terminal fall velocity distribution as well as microphysical rain properties can be derived.
+==== Multi-Filter Rotating Shadowband Radiometer ====
+The [[instruments:mfrsr:mfrsr|Multi-Filter Rotating Shadowband Radiometer]] (MFRSR) allows the retrieval of aerosol optical depth, aerosol size information as well as cloud optical depth for single-layer “horizontally homogeneous” liquid clouds.
+==== Radiation sensors =====
+A complete surface radiation balance is possible with the [[instruments:radiation:radiation|radiation sensors]] measuring at JOYCE.
+==== Surface precipitation =====
+Surface precipitation is measured with a standard [[instruments:pluvio:pluvio|Pluvio]] gauge (weighing principle) as well as with an optical didrometer [[instruments:parzivel:parzivel|Parsivel]] yielding information on the size and fall velocity of the precipitation particles.
