Simulation of sub-millimetre atmospheric spectra for characterizing potential ground-based remote sensing observations

first_imgThe sub-millimetre is an understudied region of the Earth’s atmospheric electromagnetic spectrum. Prior technological gaps and relatively high opacity due to the prevalence of rotational water vapour lines at these wavelengths have slowed progress from a ground-based remote sensing perspective; however, emerging superconducting detector technologies in the fields of astronomy offer the potential to address key atmospheric science challenges with new instrumental methods. A site study, with a focus on the polar regions, is performed to assess theoretical feasibility by simulating the downwelling clear-sky sub-millimetre spectrum from 30 mm (10 GHz) to 150 μm (2000 GHz) at six locations under annual mean, summer, winter, daytime, nighttime and low humidity conditions. Vertical profiles of temperature, pressure and 28 atmospheric gases are constructed by combining radiosonde, meteorological reanalysis, and atmospheric chemistry model data. The sensitivity of the simulated spectra to the choice of water vapour continuum model and spectroscopic line database is explored. For the atmospheric trace species hypobromous acid (HOBr), hydrogen bromide (HBr), perhydroxyl radical (HO2) and nitrous oxide (N2O) the emission lines producing the largest change in brightness temperature are identified. Signal strengths, centre frequencies, bandwidths, estimated minimum integration times and maximum receiver noise temperatures are determined for all cases. HOBr, HBr and HO2 produce brightness temperature peaks in the mK to K range, whereas the N2O peaks are in the K range. The optimal sub-millimetre remote sensing lines for the four species are shown to vary significantly between location and scenario, strengthening the case for future hyperspectral instruments that measure over a broad wavelength range. The techniques presented here provide a framework that can be applied to additional species of interest and taken forward to simulate retrievals and guide the design of future sub-millimetre instruments.last_img read more

Thai plastics giant Indorama Ventures looks to quadruple renewable energy use in next 10 years

first_img FacebookTwitterLinkedInEmailPrint分享Bloomberg:Indorama Ventures Pcl, the world’s top producer of material used in plastic bottles and polyester, plans to quadruple its use of renewable energy over the next decade as part of efforts to lower greenhouse gas emissions.The Bangkok-based company will increase solar, wind and other renewable energy sources at its more than 120 manufacturing facilities worldwide to 30% of its power bill in 2030, said Chief Sustainability Office Yash Lohia. That’s an increase from 6%, he said, adding the move will help the company’s efforts to reduce its carbon footprint.“We are going to install more solar panels at our facilities in Thailand, India and many other countries,” Lohia, the 33-year-old son of Indorama’s billionaire founder Aloke Lohia, said in an interview Tuesday. “We will also buy more clean energy from other developers to demonstrate our effort to reduce greenhouse gas emissions.”Thai power producers including Gulf Energy Development Pcl, and B. Grimm Power Pcl are also accelerating investments in renewable energy as climate-change concerns prompt governments to turn to cleaner sources. Southeast Asia’s second-biggest economy plans to add at least 56,000 megawatts of new electricity capacity by 2037, with almost four-fifths of the amount set to come from renewables, according to the energy ministry’s website.Indorama is also actively seeking recycling business acquisitions as part of a $1.5 billion spending plan to increase its reuse of plastic bottles in the production of polyethylene terephthalate, or PET, said Lohia.[Anuchit Nguyen]More: Thai petrochemicals giant to add green power to cut carbon print Thai plastics giant Indorama Ventures looks to quadruple renewable energy use in next 10 yearslast_img read more

Looking for growth? Lead with mobile

first_img 17SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr,Anne Legg Anne Legg, founder and principal of THRIVETM Strategic Services THRIVE works with credit unions to develop transformational business strategies from their business insights to grow in a competitive, highly regulated … Web: https://www.anneleggthrive.com Details For a while now, credit unions have been starting the member journey with a loan relationship to achieve growth, while positioning the delivery channels as secondary. It makes perfect sense given the structure of the business model.However, the world of personal finance is changing. Today the delivery channel experience is now primary. In many cases, members engage in mobile first before they ever enter a physical retail structure. Members want control over their finances, delivered in the form of effortless, instant interactions that don’t interrupt their lives. In this environment, credit unions must understand the needs of this new member and remain focused on enabling the control, convenience and speed that they demand.A recent Fiserv Consumer Trends Survey found that Increases in mobile phone ownership are also driving increases in mobile banking usage, with 48% of smartphone-owning households using mobile banking.Specifically:8 of 10 of U.S. households (86 million) with Internet access now use online bankingOf these households who access their accounts via online banking an average of 10 per month with 24% of them accessing their accounts daily!While this data may not be startling to some, what is interesting is the graph below which indicates members who use digital banking (defined as online banking, mobile and electronic payments) are more likely to use other revenue-generating services.Source: Fiserv Consumer Trends Survey 2015A word of caution to those getting ready to push their mobile and digital offerings to their members. Make certain that they deliver a 360-degree experience to your member that is Immediate, convenient and easy to use. This is a standard expectation, not the exception.If your offering delivers, then lead with lead with your mobile/digital and the loans will follow.last_img read more

First confirmed case of COVID-19 in IN: Risk is still low

first_imgGovernor Eric J. Holcomb and the Indiana State Department of Health (ISDH) announced today the first presumptive positive case of COVID-19 in a Marion County resident with a recent history of travel to Boston. To ensure continued coordination, Gov. Holcomb is issuing a public health emergency declaration.A presumptive positive case means the patient has tested positive at the ISDH Laboratories. Samples will be sent to the CDC for final confirmation.State Health Commissioner Kris Box, M.D., FACOG, said the adult patient has been in self-quarantine since arriving back in Indianapolis and that the risk to the general public is low.Dr. Box stated that the individual called the Department of Health on Thursday to report that he had symptoms of the virus and was directed to go to the emergency room at Community North where a team of health care providers met him in the parking lot at took him to isolation, away from the rest of the facility.  The individual has mild symptoms and is currently under the self-quarantine outside of a hospital according to Dr. Box.  80 to 85% of all cases are mild cases according to Dr. Box.  The majority of the death in the US is due to the spread in a high-risk long term care facility according to Dr. Box.  Prevention is still the key currently.  Ripley County Medical Director Dr. David Welsh stated that Ripley County is ready to handle any issues and reminds everyone to “practice what your mom taught you such as washing your hands, covering your cough, and stay home if you are sick”.  Dr. Welsh also recommends that if you think you are showing signs of illness, please call ahead to your health care provider so that they are prepared to take care of you as best as possible.  Dr. Welsh also recommend to stay up-to-date on the latest information, check out the Ripley County Department of Health website that has great information including links to the Indiana State Department of Health and The Centers for Disease Control websites.last_img read more

England’s Cath wins British senior title

first_img19 Sep 2014 England’s Cath wins British senior title England’s Cath Rawthore has completed a spectacular season by winning the senior women’s British championship at Royal Dornoch in Scotland.It’s her third big success of the year, having previously won the English senior stroke play and helped England to become European senior team champions.Cath, from Sale in Cheshire, (image © LGU) commented: “I must say it’s a good feeling to hold the English and British titles and the European team gold all in one season. I will certainly look back on 2014 with pride.”She gradually moved up the leaderboard in the British championship, starting off in ninth place, edging up to eighth after the second round and then became leader in the clubhouse after returning a final round of two-under par 74. It gave her a one-under par total for the event which proved unbeatable.At the start of the final round Cath had been eight shots off the lead, set by Leicestershire’s Helen Lowe, and had not expected to leapfrog the leaders.“I couldn’t believe it. I literally had no clue when I came off the course that I was in contention and when we went to do the cards I was told I was leader in the clubhouse.“Then news came filtering back that the leading competitors had dropped shots and it looked like I would win. I refused to believe it until all scores were in.”She won by two shots from Scotland’s Mary Tain. Two other members of England’s winning European team were also in the top ten. Lulu Housman (Highgate, Middlesex) tied third on two-over par, while Amanda Mayne (Saltford, Somerset) shared eighth place on five over.  Helen Lowe (Scraptoft), who led for the first two rounds, tied sixth on four over.Cath is playing only her second season of senior golf and has made a rapid rise to the top. She made her England debut last year, having made an instant impact with impressive results in the national championships.last_img read more
