      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 water in its snow and glaciers than any place on Earth outside the poles, and more than a billion people rely on it for drinking and irrigation. The study team used satellite estimates and modeled precipitation data to project how changing rainfall patterns in the region might affect landslide frequency. The study team found that warming temperatures will cause more intense rainfall in some areas, and this could lead to increased landslide activity in the border region of China and Nepal.

Credit: NASA Earth Observatory  Bushfires have raged in Victoria and New South Wales since November 2019, yielding startling satellite images of smoke plumes streaming from southeastern Australia on a near daily basis. The images got even more eye-popping in January 2020 when unusually hot weather and strong winds supercharged the fires. Narrow streams of smoke widened into a thick gray and tan pall that filled the skies on January 4, 2020. Several pyrocumulus clouds rose from the smoke, and the towering clouds functioned like elevators, lifting huge quantities of gas and particles well over 10 kilometers (6 miles) above the surface—high enough to put smoke into the stratosphere.

NASA researchers are using data from the Microwave Limb Sounder (MLS) instrument onboard the Aura satellite to track atmospheric carbon monoxide (CO) levels from the fires in Australia. Carbon monoxide is one the main trace gases emitted from fires and can be used to help track the path of smoke plumes. Carbon monoxide can also be used to track smoke which is injected directly to high altitudes from explosive fires.   This animation of Aura Microwave Limb Sounder (MLS) data shows carbon monoxide (CO) levels around Australia from December 25th, 2019 to January 20th, 2020. The color scale visualizes CO concentrations from 0 to 300 parts per billion (ppb), although much higher concentrations were measured briefly in some regions.

The above animation shows carbon monoxide (CO) levels in the region from December 25th, 2019 to January 20th, 2020. These concentrations were measured at an atmospheric pressure of 215 hectopascals (hPa), which is roughly 11km in altitude over southern Australia. Atmospheric pressures through the depth of the atmosphere, as measured in hPA’s, are used in meteorology as units of altitude.

The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology created this Damage Proxy Map (DPM) depicting areas that are likely damaged as a result of the November 26, 2019 earthquakes in Albania. The map was derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1 satellites, operated by the European Space Agency (ESA). The images were taken before (November 14, 2019 and November 20, 2019) and after (November 26, 2019) the sequence of earthquakes. Credit: Contains modified Copernicus Sentinel data, processed by ESA. Analyzed by the NASA-JPL/Caltech ARIA team. This task was carried out at JPL funded by NASA.  During a recent U.S. State Department “Observations and Communications Roundtable” meeting, NASA Disasters Program personnel briefed a delegation of several Italian disaster preparedness and response agencies on the work in which the program is engaged. One of the Italian delegation subsequently reached out to Disasters with a specific request for information on damage to structures in the epicentral region of an Albanian earthquake which occurred on Tuesday, November 26th, 2019. Disaster-affiliated researchers from the Advanced Rapid Images and Analysis (ARIA) team at NASA’s Jet Propulsion Laboratory were able to provide a damage proxy map that was then released to Italian officials.

In December 2019 and January 2020 Australia has experienced widespread and severe fires causing extensive damage to the local ecosystem and communities and blanketing the surrounding regions in smoke. By studying data from multiple Earth-observing satellites and different types of sensors, NASA researchers can get a more comprehensive understanding of the extent of the fires and their impact to the surrounding communities.

Credit: NASA Crew Earth Observations (CEO) On January, 4th 2020, astronauts flying 17,500 miles per hour onboard the International Space Station (ISS), captured several photographs of smoke plumes from fires in New South Wales and Victoria, spreading off the east coast of Australia into the Tasman Sea. On the ground, uncontrolled fires were exacerbated by extremely dangerous wind conditions and temperatures reaching record highs of 45⁰ Celsius (113⁰F). Reporters in Mallacoota, Victoria witnessed smoke so thick that they described it as being “like midnight at 3.30 in the afternoon.”

On December 16th, 2019 NASA’s Terra satellite flew over the eastern coast of Australia, capturing 3D data on the height of smoke plumes emanating from the fires with its Multi-angle Imaging SpectroRadiometer (MISR) instrument. Using data from this overpass, the NASA Disasters Program in collaboration with the Active Aerosol Plume-height (AAP) project has developed the first ever interactive 3D visualization of MISR fire plume-height data, which demonstrates the new 3D capabilities of the NASA Disasters Mapping PortalView Fullscreen on the NASA Disasters Mapping Portal The above interactive map allows you to view and explore this MISR smoke plume data in 3D. You can click on the images at the bottom to view the data from several pre-selected angles. These data show that in some areas the smoke plumes reached heights of more than 4 kilometers above the surface at the time of this satellite overpass. The plume heights are represented as spheres with progressively lighter colors for higher elevation, and the height has been visually exaggerated by 20x to better see the details in the data. The same data is also shown on the ground in 2D, with darker blues and purples indicating lower altitude plumes and lighter greens and yellows indicating higher altitudes. The color bar to the right shows the derived plume heights corresponding to the colors in the 2D data. In addition, “hot spot” data from Terra’s MODerate resolution Imaging Spectroradiometer (MODIS) instrument is shown as red spheres on the ground, indicating areas of active fires. The base layer of natural-color imagery is from MISR's nadir-viewing camera.

On New Year Eve 2019 a series of massive thunderstorms generated by devastating fires across the states of New South Wales and Victoria in Australia produced a gigantic smoke layer of 1.75 million square kilometers across the Tasmanian Sea, as observed by the VIIRS and OMPS instruments onboard the NOAA/NASA Suomi-NPP satellite (figure 1).

NASA scientists using data from its NOAA/NASA Suomi NPP satellite, has traced the movement of the smoke coming off the Australian fires across the globe showing that it has circumnavigated the Earth. In an image created from data gathered by the Ozone Mapping and Profiler Suite (OMPS) Nadir Mapper on Suomi NPP, a black circle shows the smoke which had been traced from its origins coming back to the eastern region of Australia after having traveled around the world. Suomi NPP carries carry five science instruments and is the first satellite mission to address the challenge of acquiring a wide range of land, ocean, and atmospheric measurements for Earth system science while simultaneously preparing to address operational requirements for weather forecasting. Suomi NPP also represents the gateway to the creation of a U.S. climate monitoring system, collecting both climate and operational weather data and continuing key data records that are critical for global change science.
