Posted on March 13, 2017Carbon dioxide levels measured at NOAA’s Mauna Loa Baseline Atmospheric Observatory rose by 3 parts per million to 405.1 parts per million (ppm) in 2016, an increase that matched the record jump observed in 2015.
Posted on March 6, 2017Temperatures recorded during a four-day period in late February 2017 across the central and eastern United States were extraordinary for the end of meteorological winter—December through February.
Posted on February 2, 2017Rising sea levels threaten the coastal U.S., low-lying but densely populated regions like New York City are rethinking their approach to the built environment. A new National Oceanic and Atmospheric Administration report warns that in the worst cases, parts of America could experience sea-level rises of as much as eight feet by 2100.
Posted on January 26, 2017GOES-16 weather satellite releases first pictures with four times the resolution of existing GOES spacecraft. The higher resolution will allow forecasters to pinpoint the location of severe weather with greater accuracy.
Posted on January 18, 2017Record warmth three years in a row: 2016 Average Global Temperature came in as 58.69 degrees. The temperature record has been broken five times since the start of the 21st century. Year ends with third warmest December on record for the globe.
Posted on December 13, 2016Most of the advanced remote sensing instruments (e.g., radar, lidar, microwave imager/sounder, hyper-spectral radiometers) are placed on Low Earth Orbiting (LEO) satellites. Their revisit time of a specific location on Earth is about 2 -12 hrs. As such, it is difficult to use LEO satellites to monitor or study a fast-evolving phenomenon such as severe storms. On the other hand, geostationary satellites (GEO) can easily capture these fast processes but lack advanced instruments (e.g., no microwave sensors, nor radar or lidar). In this short talk, I will discuss possibly solutions and propose ways to use existing LEOs for studying fast-evolving processes in atmospheric and climate sciences.
Posted on November 19, 2016GOES-R, the first of NOAA’s highly advanced geostationary weather satellites, lifted off from Cape Canaveral, Florida, at November 19th 2016. The satellite will boost the nation’s weather observation network and NOAA’s prediction capabilities, leading to more accurate and timely forecasts, watches and warnings.
