High Temperatures in the San Francisco Bay Area

On June 21st, 2022, the San Francisco Bay Area experienced high temperatures as a hot mass of air remained over the region. San Francisco reached 92 degrees Fahrenheit, Oakland reached 98 degrees Fahrenheit, and San Jose reached 102 degrees Fahrenheit. The Land Surface Temperatures at 12:22 PM PDT ranged from 60 degrees Fahrenheit to 150 degrees Fahrenheit for this region with water temperatures ranging from 50 degrees Fahrenheit to 90 degrees Fahrenheit. ECOSTRESS is a thermal instrument on the International Space Station that measures the temperature of the ground, which is hotter than the air temperature during the day. It was launched to the space station in 2018. Its primary mission is to identify critical thresholds of water use and water stress in plants and to detect the timing, location, and predictive factors leading to plant water uptake decline and/or cessation. The nature of the high-resolution data provided by ECOSTRESS allows it to record heat related phenomena such as heat waves, droughts and wildfires. https://photojournal.jpl.nasa.gov/catalog/PIA25441
