On June 19, 2004, NASA launches Aura, a next generation Earth-observing satellite. One of several instruments on the Aura satellite is the Ozone Monitoring Instrument (OMI). OMI is a contribution of the Netherland’s Agency for Aerospace Programs (NIVR) along with the Finnish Meteorological Institute (FMI). OMI will continue the TOMS record for total ozone and other atmospheric parameters related to ozone chemistry and climate.

Every year, sea ice fluctuates through the seasons, growing in the winter and shrinking in the summer. This year, Arctic sea ice reached its annual maximum on March 13, 2019. It wasn’t a record low, but it continued a trend of declining sea ice maximums and minimums.

“The 2015-2016 El Niño event brought weather conditions that triggered regional disease outbreaks throughout the world, according to a new NASA study that is the first to comprehensively assess the public health impacts of the major climate event on a global scale.
El Niño is an irregularly recurring climate pattern characterized by warmer than usual ocean temperatures in the equatorial Pacific, which creates a ripple effect of anticipated weather changes in far-spread regions of Earth. During the 2015-2016 event, changes in precipitation, land surface temperatures and vegetation created and facilitated conditions for transmission of diseases, resulting in an uptick in reported cases for plague and hantavirus in Colorado and New Mexico, cholera in Tanzania, and dengue fever in Brazil and Southeast Asia, among others.”

“On February 27, 2019, we celebrated five years in orbit for the NASA/JAXA Global Precipitation Measurement mission, or GPM. Launched from Japan on February 27, 2014, GPM has changed the way we see precipitation. It has provided unprecedented three-dimensional views of precipitation light rain to intense thunderstorms. To mark its five years, we’re looking back at five big moments in GPM’s history of observing storms.”

“A NASA F/A-18 performs the quiet supersonic dive maneuver of NASA’s Armstrong Flight Research Center in California. The dive include climbing to 50,000 feet, followed by a supersonic, inverted dive. This creates shock waves in such a way that they are quieter in a specific area. The dive has been used in support of NASA’s Commercial Supersonic Technology project, to study perception feedback provided by members of the public.”
