Substorm-induced energetic electron precipitation: Impact on atmospheric chemistry

first_imgMagnetospheric substorms drive energetic electron precipitation into the Earth’s atmosphere. We use the output from a substorm model to describe electron precipitation forcing of the atmosphere during an active substorm period in April–May 2007. We provide the first estimate of substorm impact on the neutral composition of the polar middle atmosphere. Model simulations show that the enhanced ionization from a series of substorms leads to an estimated ozone loss of 5–50% in the mesospheric column depending on season. This is similar in scale to small to medium solar proton events (SPEs). This effect on polar ozone balance is potentially more important on long time scales (months to years) than the impulsive but sporadic (few SPE/year versus three to four substorms/day) effect of SPEs. Our results suggest that substorms should be considered an important source of energetic particle precipitation into the atmosphere and included in high-top chemistry-climate modelslast_img read more

Land Registry-backed ‘home buying passport’ proptech app about to launch

first_img A tech-based home buyer passport is about to launch that will enable agents to qualify buyers, purchasers to prove to agents that they are serious and vendors to understand more about people making offers.Called Hipla, it is already being trialled with several estate agents and vendors prior to its consumer launch, which is imminent.Hipla, which has some similarities to Labour’s doomed Home Information Packs, has been a part of the current government’s Geovation Accelerator Programme for the past 12 months.Geovation is a joint venture between the Land Registry and Ordnance Survey to promote tech innovation in the housing market.Proptech“Receiving the backing, guidance and help from HM Land Registry, Geovation, and Ordnance Survey has helped our early stage start-up gain a much steadier footing than it otherwise would have done,” says Hipla founder Adam Phillips (below).“Their help with early stage funding, office space, data and market insights has been invaluable.“And their support has meant we are now in a much better position to deliver on our objectives of improving the home buying process.”Phillips’ comments were made at the launch of this year’s Accelerator programme, which features seven start-ups including a drone airspace management service, a digital concierge app called Winston and RenKap, an affordable homes marketplace.“We offer a founder-friendly environment, great mentors, high-quality workshop content and, almost uniquely, a dedicated software development team in house, who work hand in hand with our companies to build and release their first products,” says Alex Wrottesley, Head of Geovation.Hipla HIPs Home Information Packs proptech April 17, 2019Nigel LewisOne commentCuan Ryan, Butler Sherborn Butler Sherborn 17th April 2019 at 10:13 amIt doesn’t appear to have any similarities to the Home Information Pack at all! The HIP was “doomed” only because David Cameron decided to dispense with it on day 1 of his time in Downing Street with the same amount of forethought he evidently gave to referenda on Scotland and Europe. HIPs, while regarded as a nuisance by many, were actually gaining traction and were beginning to speed the conveyancing process by providing valuable information at a very early stage. I’m sure the hipla app will be a helpful tool at some stage but I cannot see it contributing to solving the biggest problem in the British property market – the time it takes from agreeing a sale to exchange of contracts and the fact that buyer and seller are in no way committed to the deal until that elusive ‘exchange of contracts’. An app or a proptech tool that would provide truly valuable information to the solicitors at the outset of a transaction (a vendor passport too) would be truly welcome in the absence of a law or mechanism to bind buyer and seller more quickly after a deal is agreed. A local solicitor proudly informed us recently that the average time between exchange and completion (in their firm) is now 11 weeks!Log in to ReplyWhat’s your opinion?
