![]() ![]() The strongest SAR winds are not completely encircling the eye. The image below compares the SAR observations with the Target Himawari Band 13 (Clean Window, 10.4 µm) image. The RCM-2 satellite made another overpass over Mawar, this time at 0830 UTC on 23 May (previous SAR Observations are discussed here and here). DPRINT (formerly OPEN-AIIR) estimates of Mawar’s intensity through 1420 UTC on (Click to enlarge) Such cycles are challenging to predict in advance. Microwave observations of the eyewall structure ( here), can be used to monitor the possibility of an Eyewall Replacement Cycle (ERC), which cycle will be responsible for short-time period variations in typhoon strength from now through landfall on/near Guam. The DPRINT product (formerly called Open-AIIR), a Machine-Learning tool that estimates winds based on satellite presentation, available at the SSEC Tropical Weather Website, suggests a peak in intensity occurred around 1000 or 1100 UTC on 23 May. Maximum Potential Intensity Pressure (in hPa/mb), 0500 UTC on (Click to enlarge) Based on the analysis of heat content in the ocean (from the SSEC Tropical Weather Website), below, Mawar is close to its maximum strength. The 0600 UTC update from the Joint Typhoon Warning Center reported a central pressure near 923 mb. The eye is seemingly in steady state from about 0300-0900 UTC, after which time its size shrinks. The animation above shows a well-developed symmetric storm with good outflow from all quadrants. ![]() Himawari-9 Infrared Imagery, above, shows Mawar as it develops and eye and strenghtens to Super Typhoon status. Himawawri-9 Band 13 Clean Window Infrared (10.4 µm) imagery, 1702 UTC on through 1212 UTC on."What we have right now is really, truly advanced and state of the art," said Yoe. Although NOAA is already developing the next-generation satellites that will follow, like the Geostationary Extended Observations ( GeoXO) satellites, the GOES-R satellites still carry advanced instruments that offer ever-expanding contributions to weather forecasting and climate science. The satellites will also be an important tool in continuing to monitor global climate change, from tracking changes in Earth's clouds to observing the impacts of climate change on Earth's surface, like changes in vegetation and wildfire frequency. "We're still learning all the time how to use these instruments," he said. He said the lightning mapper even detected a meteor that burned up over Pittsburgh on New Years' Day, even though the system wasn't designed to detect meteors. "More and more, we find we're able to use the imager, for example, to help us detect and fight wildfires, because it's so much more sensitive than the previous imager," Yoe told. ![]() Earth from space: The amazing photos by the GOES-16 satellite Powerful Landsat 9 satellite beams home 1st photos of Earth Along with being a crucial source of weather data, GOES satellites collect a wide variety Earth observations, including information on the atmosphere and oceans. The satellites also carry a lightning tracker, which helps accurately forecast thunderstorm, hail and tornadoes. Space weather is expected to strengthen as the sun reaches the peak of its 11-year activity cycle around 2025.ĭata from GOES satellites' ABI instruments enables reliable weather forecasting, severe storm warnings and hurricane tracking. Along with other instruments on the satellite, the magnetometer will help detect space weather, which can cause power, communications and navigational outages on Earth. The new satellite will also have an improved magnetometer, which can detect variations in the Earth's magnetic field. The ABI on GOES-17 glitched shortly after its launch in 2018 and does not work properly when it is directly facing the sun, which happens at times during the spring and fall. GOES-T will carry largely the same array of technology as previous GOES-R satellites, but its Advanced Baseline Imager (ABI), the main weather imaging system on the satellite, includes an upgraded cooling system. GOES-17 will become a standby satellite once GOES-18 is active the new satellite is expected to operate until about 2030. Together, GOES East and West cover much of the Western Hemisphere, from New Zealand to the western coast of Africa. The new spacecraft will replace GOES-17, which is currently serving as GOES-West. GOES-T, which will become GOES-18 once it reaches orbit, will join GOES-16, which was launched in 2016 and is serving as the GOES-East satellite. ![]()
