Worldview Image of the Week

Tropical Cyclone Jasper over Queensland, Australia

Base image captured Dec 13, 2023, by the VIIRS instrument aboard the joint NASA/NOAA Suomi NPP satellite, overlaid with IMERG Precipitation Rate.

True-color corrected reflectance image of Tropical Cyclone Jasper crossing over Queensland in northeastern Australia on December 13, 2023, acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite. The true-color image is overlaid with the Integrated Multi-satellitE Retrievals for GPM (IMERG) Precipitation Rate layer, which displays rain rate and snow rate in millimeters per hour (mm/hr); red/orange colors indicate areas of heaviest rain. IMERG Precipitation Rate is estimated by the IMERG algorithm, which uses passive-microwave data from the Global Precipitation Measurement (GPM) constellation of satellites along with infrared data from geosynchronous satellites.

Tropical Cyclone Jasper made landfall over a fairly sparsely populated area as a Category 2 storm, with winds of up to 140 kilometers per hour (87 miles per hour). Jasper is the first tropical cyclone of the season to hit Australia. The IMERG Precipitation Rate layer shows heavy rainfall (red/orange colors) indicating rain rates of more than 10 mm/hour (slightly less than 0.4 inches/hour) near the coastal city of Cairns.
