Seychelles Instrumentation

The equipment used in Seychelles during the observational period is described below:

The ASIRI: RAWI project's observational period was from February 1, 2015 to March 15, 2015.

A detailed list of Radiosonde_Seychelles_1the instrumentation used is found below. For major instruments, a photograph is provided to contextualize the location and the sophistication of the equipment. For major equipment, a brief description of the data collected further explains its use.
