Bangladesh has a long history of deadly and costly storms. Because these storms are so localized, they can be notoriously difficult to forecast, especially without access to the most advanced weather prediction technology. Researchers have created a new tool to boost the country’s ability to forecast severe weather. The SERVIR program - a joint initiative of NASA, USAID, and leading geospatial organizations in Asia, Africa, and Latin America - and the Bangladesh Meteorological Department (BMD) recently launched the High-Impact Weather Assessment Toolkit (HIWAT), a web-based tool that

The Lightning Imaging Sensor is a small, highly sophisticated instrument that detects and locates lightning over the tropical region of the globe. Looking down from a vantage point aboard the Tropical Rainfall Measuring Mission (TRMM) observatory, 250 miles (402 kilometers) above the Earth, the sensor provides information that could lead to future advanced lightning sensors capable of significantly improving weather "nowcasting." Using a vantage point in space, the Lightning Imaging Sensor promises to expand scientists' capabilities for surveying lightning and thunderstorm activity on a global...
