Processing remote weather data with a Raspberry Pi

Whither the Weather

A Raspberry Pi directs data collection from a network of weather stations in the Caribbean, processes the data, and makes it available on a web page.

Climate, weather, and hydrological data collection and archiving is an integral part of the services provided by the Caribbean Institute for Meteorology and Hydrology (CIMH) [1], located in Barbados. Data collected in these archives is integrated into global databases that are used to assess and monitor global and regional climate change. These data are also important for designing national and community-based climate adaptation strategies, so easy access to the data is critical.

Apart from training technical personnel for their respective National Meteorological and Hydrological Services (NMHSs) positions across the Caribbean region, I am frequently requested to assist with the installation of meteorological and hydrological equipment throughout the region. These requests can come directly from an NMHS, but most requests come directly from projects funded by regional and international development agencies. Regardless of the source of the request, a common question asked is, "Can I access the data?"

Early Windows Solution

Under the Enhancing Resilience to Reduce Vulnerability in the Caribbean (ERC) Project [2] funded by the Government of Italy from 2009 to 2013 and executed by the United Nations Development Programme Office for Barbados and the Organization for Eastern Caribbean States, 14 full Sutron automatic weather stations (AWSs) [3] were installed at locations in the Eastern Caribbean, including the CIMH campus. A Windows machine was purchased for the Sutron software, XConnect [4], for each AWS system. This Windows-based software downloads and archives data onto local machines on each island.
