El fenómeno de los refugiados ambientales en Haití y su repercusión en la seguridad regional (2010-2015)

Esta monografía busca analizar cómo el fenómeno de los refugiados ambientales que se generó a partir del terremoto en Haití de 2010, ha influido sobre el complejo de seguridad en la región de el Caribe, desde el 2010 hasta el 2015, teniendo en cuenta la crisis social provocada por el desastre ambiental, ya que en razón de la carencia de estatus legal y de amenazas interdependientes y multidimensionales obligó a los Estados del área a modificar sus políticas de seguridad, mediante la interacción de los países, puesto que se presentaron diferentes cambios en las relaciones del complejo de seguridad, lo cual determino nuevas transformaciones en la securitización de la región. Esta monografía recurrirá a la teoría de Complejos de Seguridad Regional de autores como: Barry Buzan, Ole Waever, Derrick Frazier y Robert Stewart.

The UK-Canada Agreement on mutual support of missions abroad: loyalty compromised? CEPS Commentary, 18 October 2012

The UK and Canada recently signed a Memorandum of Understanding aimed at allowing the two countries to optimise their respective diplomatic resources by sharing embassy and consulate sites, the joint acquisition, supply and use of services, as well as collaboration on crisis response, consular services, security, diplomatic mail, information management and IT. This CEPS Commentary argues that the MoU on Mutual Support of Missions Abroad runs counter to the spirit of loyal cooperation, in particular in the realm of EU foreign policy. It also raises challenges to coherence, consistency and effectiveness of EU action in policy areas concerning visas, trade and consular protection. Moreover, the agreement may throw a spanner in the works of EU solidarity and the creation of a stronger EU identity, both internally and externally

Far infrared filters for the GALILEO-Jupiter and other missions

Extrapolation of PbTe/II-VI multilayer interference-filter technique from 20 to beyond 40µm is described and PbTe transparency reviewed; improvements below 20µm are reported. A composite filter cutting on steeply at 40µm is described that uses absorptive films of ZnS and As2S3, thin Quartz, and supplementary multilayer interference. Absorptive filters are described containing the II-VI compounds since these are found transparent at wavelengths shorter and longer than their reststrahl.

L'effet de compensation morale ou comment les 'bonnes actions' peuvent aboutir à une situation indésirable

Des recherches récentes arguent qu’une « bonne action » pourrait contribuer à « désinhiber » l’individu en lui permettant d’entreprendre des actions « moins souhaitables » par la suite. Cet effet de compensation morale reste un domaine peu étudié, en dépit des conséquences potentielles considérables sur l’efficacité des politiques publiques. L’objectif de notre contribution est de définir et de caractériser cet effet tout en soulignant les risques d’effets pervers associés. Nous utilisons à cet effet des études et des exemples tirés de divers domaines, comme la consommation alimentaire ou les comportements prosociaux, et identifions des pistes de recherche visant à mieux comprendre les conséquences directes et indirectes de cet effet, tout en mentionnant quelques stratégies envisageables afin d’atténuer ce biais.

Land surface temperature retrieval from Sentinel 2 and 3 Missions

In this work we explore the synergistic use of future MSI instrument on board Sentinel-2 platform and OLCI/SLSTR instruments on board Sentinel-3 platform in order to improve LST products currently derived from the single AATSR instrument on board the ENVI- SAT satellite. For this purpose, the high spatial resolu- tion data from Setinel2/MSI will be used for a good characterization of the land surface sub-pixel heteroge- neity, in particular for a precise parameterization of surface emissivity using a land cover map and spectral mixture techniques. On the other hand, the high spectral resolution of OLCI instrument, suitable for a better characterization of the atmosphere, along with the dual- view available in the SLTSR instrument, will allow a better atmospheric correction through improved aero- sol/water vapor content retrievals and the implementa- tion of novel cloud screening procedures. Effective emissivity and atmospheric corrections will allow accu- rate LST retrievals using the SLSTR thermal bands by developing a synergistic split-window/dual-angle algo- rithm. ENVISAT MERIS and AATSR instruments and different high spatial resolution data (Landsat/TM, Proba/CHRIS, Terra/ASTER) will be used as bench- mark for the future OLCI, SLSTR and MSI instruments. Results will be validated using ground data collected in the framework of different field campaigns organized by ESA.

Concepts for a geostationary-like polar missions

An evidence-led scientific case for development of a space-based polar remote sensing platform at geostationary-like (GEO-like) altitudes is developed through methods including a data user survey. Whilst a GEO platform provides a nearstatic perspective, multiple platforms are required to provide circumferential coverage. Systems for achieving GEO-like polar observation likewise require multiple platforms however the perspective is non-stationery. A key choice is between designs that provide complete polar view from a single platform at any given instant, and designs where this is obtained by compositing partial views from multiple sensors. Users foresee an increased challenge in extracting geophysical information from composite images and consider the use of non-composited images advantageous. Users also find the placement of apogee over the pole to be preferable to the alternative scenarios. Thus, a clear majority of data users find the “Taranis” orbit concept to be better than a critical inclination orbit, due to the improved perspective offered. The geophysical products that would benefit from a GEO-like polar platform are mainly estimated from radiances in the visible/near infrared and thermal parts of the electromagnetic spectrum, which is consistent with currently proven technologies from GEO. Based on the survey results, needs analysis, and current technology proven from GEO, scientific and observation requirements are developed along with two instrument concepts with eight and four channels, based on Flexible Combined Imager heritage. It is found that an operational system could, mostly likely, be deployed from an Ariane 5 ES to a 16-hour orbit, while a proof-of-concept system could be deployed from a Soyuz launch to the same orbit.

Water waves generated by local disturbance: Serre's model validity

Water waves generated by landslides were long menace in certain localities and the study of this phenomenon were carried out at an accelerated rate in the last decades. Nevertheless, the phase of wave creation was found to be very complex. As such, a numerical model based on Boussinesq equations was used to describe water waves generated by local disturbance. This numerical model takes in account the vertical acceleration of the particles and considers higher orders derivate terms previously neglected by Boussinesq, so that in the generation zone, this model can support high relative amplitude of waves.

Analysis of the impact of rainfall assimilation during LBA atmospheric mesoscale missions in Southwest Amazon

The assimilation of satellite estimated precipitation data can be used as an efficient tool to improve the analysis of rainfall generated by numerical models of weather forecast. The system of data assimilation used in this study is cumulus parameterization inversion based on the Kuo scheme. Reanalysis were performed using the field experiment data of the LBA Project (WETAMC and DRYtoWET-AMC), where it was possible to verify an improvement in the simulations results, since the data assimilation corrects the position and the intensity of rainfall in the numerical model.
