    NASA tracks a scorching heat wave in the southwestern United States. While a scientific instrument struck the southwestern United States in early July. One mapped the high pressure dome that was installed, but the other captured the ground surface temperature. Just weeks after record Pacific Northwest temperatures, another heat wave hitting the US burned the Southwest.

    This heat wave, which began around July 7, broke or broke several records in California, Nevada, northern Arizona and southern Utah. Two instruments, NASA’s Atmospheric Infrared Sounder (AIRS) aboard the Aqua satellite, and the agency’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS), tracked the heat wave, providing visualizations of it.

    The AIRS instrument covered the southwestern US from July 1 to July 12. In captured the progress of the slow moving heat dome. Animation of AIRS data (above) shows surface air temperature anomalies: values above or below the long-term average. Surface air temperatures in warmer areas shown in pink are more than 10 degrees Fahrenheit (5.6 degrees Celsius) above average. Surface air temperature is something that people feel directly when they are outside.

    On July 8, NASA’s ECOSTRESS instrument, attached to the International Space Station, captured surface temperature data over California. In the image (middle image), the areas in red, including Death Valley, had exceeded 86 degrees Fahrenheit (30 degrees Celsius) at 7 a.m. local time, well above the average ground surface temperature for the area.

    California & Northern Arizona

    On July 9, Death Valley recorded a high air temperature of 130 F, dropping just a few degrees below the official all-time surface air temperature record of 134 F, set in 1913. On July 11 , Bishop, California hit an all-time high of 111 F and Stovepipe Wells, California set a new record for average daily temperatures of 118 F. Several other daily, monthly and all-time records were set in the inner central and southern areas from California and northern Arizona.

    California’s record-breaking intense heat wave

    From cities to deserts, California’s scorching heat is being monitored by an Earth-observing mission aboard the International Space Station. As record temperatures and major fires ravage California, NASA’s Spaceborne Ecosystem Thermal Radiometer Experiment on the Space Station (ECOSTRESS) is tracking a heat wave from low Earth orbit.

    While ECOSTRESS’s primary mission is to measure the temperature of plants as they emerge from the water, it can also measure and track heat-related events such as heat waves, wildfires, and volcanoes.

    at 3:56 pm. 14 PDT (6:56 p.m. EDT), as the space station passed over Los Angeles, ECOSTRESS was able to take a snapshot of the rise in Earth’s surface temperature across the county, home to more than 10 million people.

    The temperature of the earth’s surface is the temperature of the earth rather than the temperature of the air above it. In the first image, ECOSTRESS measured a temperature range of approximately 70 to 125 ° F (21 to 52 ° C), being the coldest on beaches and mountains.

    The highest surface temperatures, in deep red, were found northwest of downtown Los Angeles in the San Fernando Valley. The instrument also captured the ranch fire, which was visible in the center of the image as it burned. The Earth’s surface temperature exceeded 125 ° F (52 ° C), between which it peaked at 128.3 ° F (53.5 ° C). The cities of Van Nuys and Encino.

    This ECOSTRESS temperature map shows land surface temperatures around Death Valley in California’s Mojave Desert during a heat wave on August 16, 2020. Those afternoon peaks were within the range of morning surface temperatures, ECOSTRESS measured two days later in Death Valley, part of California’s Mojave Desert.

    As shown in the second image, from 8:50 a.m. PDT (11:50 a.m. EDT) on August 16, ECOSTRESS recorded a high temperature of 122.52 degrees Fahrenheit (50.29 degrees Celsius) near Furnace Creek in Death Valley National Park.

    Earth Sciences

    The ECOSTRESS observations have a spatial resolution of approximately 77 by 77 yards (70 by 70 meters), allowing researchers to study surface temperature conditions down to the size of a football field. Due to the unique orbit of the space station, the mission can acquire images of the same region at different times of the day, unlike satellites in other orbits that cross each region at the same time.

    For example, this is beneficial when monitoring plant stress in the same area throughout the day.

    The ECOSTRESS radiometer is deployed on the International Space Station (ISS) at the Japanese Experimental Module – External Facility (JEM-EF) Site 10. At this location, the radiometer scan is perpendicular to the speed of the ISS. 

    NASA’s Earth System

    The ECOSTRESS mission launched to the space station on June 29, 2018. NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, builds and manages the mission for the Earth Sciences Division at the Science Mission Directorate at NASA Headquarters in Washington.
