GPM Flies Over Extratropical Cyclone Dennis in the U.K.

Extratropical Storm Dennis, February 15, 2020
Tuesday, February 18, 2020
Storm Dennis is an extratropical cyclone that developed over the continental United States before undergoing explosive intensification as it crossed into the North Atlantic. On February 15 shortly after this GPM overpass, Dennis reached its minimum central pressure of 920 mb, which is reported to be the second-lowest on record for a North Atlantic winter storm. The eye can be seen south of Iceland, while rain bands to the south caused severe flooding across the British Isles. Text & Visualization by Jason West (NASA / KBR)

Climate Change and Landslide Risk in Asia

Landslide Risk in High Mountain Asia
Tuesday, February 11, 2020
More frequent and intense rainfall events due to climate change could cause more landslides in the High Mountain Asia region of China, Tibet and Nepal, according to the first quantitative study of the link between precipitation and landslides in the region. The model shows landslide risk for High Mountain Asia increasing in the summer months in the years 2061-2100, thanks to increasingly frequent and intense rainfall events. Summer monsoon rains can destabilize steep mountainsides, triggering landslides. Credits: NASA's Earth Observatory/Joshua Stevens High Mountain Asia stores more fresh...

3D Printed GPM Precipitation Data

3D Printed GPM Data from Typhoon Malakas
Wednesday, February 5, 2020
Overview Precipitation data from the Global Precipitation Measurement mission (GPM) was used to generate these 3D printed models of various tropical cyclones and storm systems from the past several years. This data was collected by GPM's Dual-frequency Precipitation Radar instrument, which utilizes Ka-band and Ku-band frequencies to measure the size, shape, and distribution of liquid and solid water particles within clouds in three dimensions. The raw radar data was then processed by algorithms at NASA's Precipitation Processing System to be converted to precipitation rates, then was further
