    SAM-2 ground-truth plan: Correlative measurements for the Stratospheric Aerosol Measurement-2 (SAM 2) sensor on the Nimbus G satellite

    The SAM-2 will fly aboard the Nimbus-G satellite for launch in the fall of 1978 and measure stratospheric vertical profiles of aerosol extinction in high latitude bands. The plan gives details of the location and times for the simultaneous satellite/correlative measurements for the nominal launch time, the rationale and choice of the correlative sensors, their characteristics and expected accuracies, and the conversion of their data to extinction profiles. The SAM-2 expected instrument performance and data inversion results are presented. Various atmospheric models representative of polar stratospheric aerosols are used in the SAM-2 and correlative sensor analyses

    HYPERLOCAL REVENUES IN THE UK AND EUROPE: Mapping the road to sustainability and resilience

    Get PDF
    During the past few years, Nesta and other strategic organisations have published research and delivered a range of resources to directly support hyperlocal media publishers to innovate their service. While there are a growing number of examples of innovative and dynamic practice, and an increasing relevance of hyperlocal media due to the shrinking footprint of traditional local print and broadcast media, our research highlights key challenges concerning sustainability (financial as well as human resource), growth and ‘findability’. As the sector continues to grow and becomes more diverse - in regards to the types of businesses and services that are producing content, the type of content being produced, the means through which content is being distributed and the ways in which local audiences are accessing and engaging with content - a more robust examination of how publishers are monetising their services is necessary. Therefore, this study undertakes an analysis of current and emerging revenue streams and the digital technologies facilitating these – the findings of which will help publishers implement positive changes to their own service. This research is aimed at online-first (but not necessarily online-exclusive) hyperlocal practitioners in the UK and in Europe, for them to use the findings and guidance to improve their ability to provide news and information to their local communities for the long term. It also provides evidence and recommendations to wider industry and policymakers in Europe in order for them to better support hyperlocal media, in regards to aspects such as the Digital Single Market, tax regulation especially in regards to organisational structure, and regulation of other areas of the digital and media sectors

    RSM Outlook Summer 2014

    #### Project Mainstream: Changing the Shape of Business (Lesa Sawahata) It has been clear for some time that finite resources, increasing commodities costs and the ever-greater demands of the world’s growing group of middle class consumers cannot be resolved with old business models. It’s time for a market evolution – and along with it, an economic revolution. #### Why the Circular Economy is a Cradle to Cradle Economy (Lesa Sawahata) RSM’s Cradle to Cradle Chair for Innovation and Quality – the only one of its kind in the world – places the faculty members behind it, and the school as a whole, right at the very heart of the global drive towards a circular economy

    Happiness and environmental quality

    Subjective wellbeing — happiness — is of increasing interest to economists, including environmental economists. There are several reasons for thinking that environmental quality (EQ), deïŹned as high levels of environmental goods and low levels of environmental ‘bads’, will be positively related to happiness. Quantitative evidence on this remains limited, however. Some papers use cross-sectional data aggregated at country level, but it is open to doubt whether these aggregated measures reïŹ‚ect individuals’ real EQ exposures. Other papers use individual-level data, but in general have spatial data at very coarse resolution, and consider a limited range of EQ variables, exclusively around individuals’ homes. This thesis reports two related strands of work. The ïŹrst designs, implements and analyses data from two new cross-sectional surveys. It builds on earlier work by using spatial data at very high resolution, and advanced Geographical Information Systems (GIS) techniques; by simultaneously considering multiple EQ characteristics, around both homes and workplaces; and by investigating the sensitivity of results to the choice of happiness indicator. The second strand develops and implements a new methodology focused on individuals’ momentary experiences of the environment. It extends a protocol known by psychologists as the Experience Sampling Method (ESM) to incorporate satellite (GPS) location data. Using an app for participants’ own smartphones, called Mappiness, it collects a panel data set comprising millions of geo-located responses from thousands of volunteers. EQ indicators are again joined to this data set using GIS. Results of the ïŹrst strand of work are mixed, but support some links between happiness and the accessibility of natural environments, providing quantitative (including monetary) estimates of their strength. The second strand demonstrates that individuals are signiïŹcantly and substantially happier outdoors in natural environments than continuous urban ones. It introduces a valuable new line of evidence on this question, which has great potential for future development

    Planning for Materials Processing in Space

    Get PDF
    A systems design study to describe the conceptual evolution, the institutional interrelationshiphs, and the basic physical requirements to implement materials processing in space was conducted. Planning for a processing era, rather than hardware design, was emphasized. Product development in space was examined in terms of fluid phenomena, phase separation, and heat and mass transfer. The effect of materials processing on the environment was studied. A concept for modular, unmanned orbiting facilities using the modified external tank of the space shuttle is presented. Organizational and finding structures which would provide for the efficient movement of materials from user to space are discussed
