Flight 15, April 26, 2011 Flight 15, April 26, 2011 Generally there was an inversion between 1000 and 1500 meters capping the boundary layer. Zeppelin Station is below this inversion. Flight 15, April 26, 2011 The boundary layer aerosol number concentration and aerosol absorption coefficient are similar to the average values measured at Gruvebadet. Flight 15, April 26, 2011 The aerosol number concentration was generally higher aloft. This layer occasionally contained absorbing aerosol (black carbon). Conclusions from Svalbard • UAS can provide high quality vertical distributions of aerosol properties. • Aerosol transport to Ny-Ålesund occurs above the boundary layer and is not necessarily sampled by ground or mountain stations. • Regular UAS measurements could provide the vertical aerosol data needed to test climate models and satellite retrievals.

    RAYMOND A. GREENWALD HIGH-FREQUENCY RADIOWAVE PROBING OF THE HIGH-LATITUDE IONOSPHERE During the past several years, a program of high-frequency radiowave studies of the high-latitude ionosphere has been developed in the APL Space Department. Studies are now being conducted on the formation and motion of high-latitude ionospheric electron density irregularities, using a sophisti­ cated high-frequency radar system installed at Goose Bay, .Labrador. The radar antenna is also being used to receive signals from a beacon transmitter located at Thule, Greenland.

The Elite Satellit is an elegant confluence of performance, features and capabilities. The look, feel and finish of this radio is superb. The solid, quality feel is second to none. The digitally synthesized, dual conversion shortwave tuner covers all long wave, mediums wave (AM) and shortwave frequencies. HD Radio improves audio fidelity and adds additional programming without a subscription fee. Adjacent frequency interference can be minimized or eliminated with a choice of three bandwidths [7.0, 4.0, 2.5 kHz]. The sideband selectable Synchronous AM Detector further minimizes adjacent frequency interference and reduces fading distortion of AM signals. IF Passband Tuning is yet another advanced feature that functions in AM and SSB modes to reject interference. AGC is selectable at fast or slow. High dynamic range permits the detection of weak signals in the presence of strong signals. All this coupled with great sensitivity will bring in stations from every part of the globe.

  • Hans Knot International Radio Report April 2016 Welcome to Another
    Hans Knot International Radio Report April 2016 Welcome to another edition of the International Radio Report. Thanks all for your e mails, memories, photos, questions and more. Part of the report is what was left after the March edition was totally filled and so let’s go with this edition in which first there’s space for a story I wrote last months after again doing some research: ‘Ronan O’Rahilly, Georgie Fame and the Blue Fames. Where it really went wrong!’ On this subject I’ve written before but let’s go back in time and also add some new facts to it: ‘Was Ronan O’Rahilly the manager of Georgie Fame?’ I can tell you there was a problem with an important instrument. When in April 1964 Granada Television came with an edition of the ‘World in action’ series, which was a production from Michael Hodges, they informed the television public about a new form of Piracy, the watery pirates. Two radio ships bringing music and entertainment under the names of Radio Caroline and Radio Atlanta. Radio Caroline was the first 20th century Pirate off the British coast with programs, at that stage, for 12 hours a day. Interviews with the Caroline people were made in the offices of Queen Magazine in the city of London and included – among others – Jocelyn Stevens and the then 23-year old Irish Ronan O’Rahilly. During this documentary it became known, which we would also read in several newspapers in the then following weeks, that Ronan O’Rahilly had started his radiostation Caroline as he couldn’t get his artists played on stations like Radio Luxembourg.

It was the most intensively measured site of the CLPX, and measurements here had the greatest temporal component of all CLPX sites. Measurements made at the LSOS were designed to produce a comprehensive assessment of the snow, soil, and vegetation characteristics viewed by the ground-based remote sensing instruments. The objective of the ground-based microwave remote sensing was to collect time series of active and passive microwave spectral signatures over snow, soil, and forest, which is coincident with the intensive physical characterization of these features. Ground-based remote sensing instruments included frequency modulated continuous wave (FMCW) radars operating over multiple microwave bandwidths; the Ground-Based Mi- crowave Radiometer (GBMR-7) operating at channels 18.7, 23.8, 36.5, and 89 GHz; and in 2003, an L-, C-, X- and Ku-band scatterometer radar system.

    REMOTE SENSING TOOLS FOR DETECTING AND QUANTIFYING LIANAS AND TREES AT THE TROPICAL DRY FOREST by Jose Antonio Guzmán Quesada A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy Department of Earth and Atmospheric Sciences University of Alberta © Jose Antonio Guzmán Quesada, 2021 ABSTRACT Lianas are woody thick-stemmed climbers that use host trees to reach the forest canopy. Studies have shown a remarkable increase in liana abundance in the last two decades, while others have shown that liana abundance is associated with detrimental effects on forest dynamics. Liana abundance presents peaks in highly seasonal forests such as the Tropical Dry Forest (TDF); regions that are under threat for frequent droughts, fires, and anthropogenic pressures. Despite their abundance and relevance in these fragile ecosystems, there are no clear research priorities that help to conduct an efficient detection and monitoring of lianas. This dissertation aims to integrate new remote sensing perspectives to detect and quantify lianas and trees at the TDF. This was addressed using passive (Chapters 2 ‒ 4) and active remote sensing (Chapter 5). Using thermography, Chapters 2 explored the temporal variability of leaf temperature of lianas and trees at the canopy. Temperature observations were conducted in different seasons and ENSO years on lianas and trees infested and non-infested by lianas. The findings revealed that the presence of lianas on trees does not affect the temperature of exposed tree leaves; however, liana leaves tended to be warmer than tree leaves at noon. The results emphasize that lianas are an important biotic factor that can influence canopy temperature, and perhaps, its productivity.

Algeria Enterprise Nationale de Radiodiffusion Sonore The Entreprise Nationale de Radiodiffusion Sonore (ENRS, the National Sound Broadcasting Company, Algerian Radio, or Radio Algérienne) is Algeria's state-owned public radio broadcasting organisation. Formed in 1986 when the previous Algerian Radio and Television company (established in 1962) was split into four enterprises, it produces three national radio channels: Chaîne 1 in Arabic, Chaîne 2 in Berber and Chaîne 3 in French. There are also two thematic channels (Radio Culture and Radio Coran), one international station (Radio Algérie Internationale broadcasting on shortwave) and many local stations. The official languages of Algeria are Arabic and Tamazight (Berber), as specified in its constitution since 1963 for the former and since 2016 for the latter. Berber has been recognised as a "national language" by constitutional amendment since 8 May 2002.
