Observations of stratospheric warmings and mesospheric coolings by the TIMED SABER instrument

Posted on

first_imgWe used temperature data from the Sounding of the Atmosphere with Broadband Emission Radiometry (SABER) on the the NASA TIMED satellite to quantify the connection between temperatures in the stratosphere and in the mesosphere and lower thermosphere. Specifically, we studied three winter periods where stratospheric temperatures were dynamically disturbed: February 2002, August, 2002, and February 2003. The SABER temperatures show a clear signature of mesospheric coolings in concert with stratospheric warmings. Mesospheric temperatures between 0.7 hPa and 0.01 hPa show a significant anticorrelation with stratospheric temperatures. For pressures <0.01 hPa, this anticorrelation breaks down, in disagreement with recent model results from a thermosphere-ionosphere-mesosphere general circulation model that suggest mesospheric coolings persist up to 110 km. Also, the lack of a clear correlation between stratospheric temperatures and those at 83–90 km suggests that measurements of the OH Meinel band temperatures at those altitudes may not be representative of the entire mesosphere.last_img read more

Credit unions need to up their data management game

Posted on

first_img“The banking sector, especially when focusing on aspects that involve core banking functions, has largely been behind in the adoption of modern computing and data technologies.”In a January 2016 research study by the Filene Research Institute (The State of Data Technology in Credit Unions: The Sink‑or‑Swim Crossroad Ahead), Professor Jignesh M. Patel argues that credit unions are falling behind when it comes to using data to make strategic decisions.The study was based on an online survey that was followed up by in-depth interviews with a sub-set of survey respondents. While the study as a whole was full of valuable insights, the results of the interviews were particularly meaningful for credit unions that want to do a better job of harnessing their data.One finding that stands out is entitled, “Data Analysis is Largely Manual”. This section of the report makes some very important observations. continue reading » 4SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblrlast_img read more
