Paraguay Flooding - June 2014
June 27, 2014 - Recently the Paraguay River, particularly through the Paraguayan capital of Asuncion, has experienced large scale flooding, causing the displacement of thousands of people. The VIIRS instrument on S-NPP has been used to capture the extent of the flooding. Here is the STAR Report for Paraguay Flooding. Below are some images of the affected areas created from VIIRS data.
