Instrumentation

The Perdigão project were instrumented with several tall Met-Masts and multiple remote sensing devices. A list of instruments and their locations is shown below.

Tower Instrumentation

Tall Met-Masts used in Perdigão during the observational period is described below:

Example of generic sensor, datalogger and communications system locations on a typical instrumented meteorological tower. The sensor suite and sensor height (including multiple levels on tall towers) is not shown in detail here.

The 52 meteorological towers, apart from the sequential numbering:

• 1 to 16: North-west transect
• 17 to 31: South-east transect
• 32 to 39: South West ridge
• 40 to 46: North-east ridge
• 47 to 53: valley
• 54 & 55: extreme (outside the central region)

As of 1 May 2017, the start of the IOP, 81% of the towers are operational and transmitting data. The progress can be tracked on the Tower Status Update spreadsheet. The typical layout of the tower instruments and communications system is shown in Figure below.
