We have installed several platforms of instrumentation around London to observe the urban climate – latest data available here.

Instrumentation Platforms

Platform 1: BT-Tower

An Eddy Correlation system has been installed at 190m on top of the BT Tower, consisting of sonic anemometer (Gill R3), infra-red hygrometer (Licor Li-7500), net radiometer (Kipp and Zonen CNR4) and weather station (Vaisala WXT520).


Platform 2: Rooftop at WCC

An Eddy Correlation system has also been installed at 18m on top of Westminster City Council (WCC) House, consisting also of sonic anemometer (Gill R3), infra-red hygrometer (Licor Li-7500), net radiometer (Kipp and Zonen CNR4) and weather station (Vaisala WXT520).


Platform 3: Remote Sensing

We operate a Halo-Photonics scanning Doppler lidar from either WCC or the King’s College London site to measure turbulence and backscatter throughout the boundary layer. Stuart Bradley at University of Auckland is developing a novel bistatic “urban sodar” in collaboration with us to scan lower levels winds and turbulence.


Platform 4: Wind-Tunnel

The Wind-Tunnel at the University of Reading has dimensions of 1500×232x232 mm. The boundary layer generated has scale 1:2000. In order to generate the boundary layer, Lego bricks are used as upstream elements. Hot-wire anemometry is used to analyse the properties of the boundary layer generated. We collaborate with Alan Robins at EnFlo.


Data-Feed From London

******A message from the ACTUAL webmaster******

Data must not be used in any way without specific consultation with a core ACTUAL team member. We expect that permission to show and analyse data will normally be granted, but there are a number of assumptions in the collecting, processing and plotting of data that will be important to understand before the data can be used. We hope and expect to collaborate with existing and new partners in the use of our data.

Have a browse through our graphical database of ACTUAL data from London, updated on a daily basis from Platforms 1, 2 and 3. Alternatively, here is a live data-feed from the weather stations on Platforms 1 and 2:
