Resúmenes

El IV Taller de Mediciones con Lidar en Latinoamérica tuvo lugar, entre los días 17 y 23 de Junio de 2007, en Ilhabela, São Paulo, Brasil. Este taller fue el más reciente paso en el desarrollo de la comunidad lidar en Latinoamérica y en la implantación de una red de lidares en la región. En los talleres anteriores se han dado pasos dirigidos a la formación de una red de lidares con la participación de alrededor de 20 investigadores y estudiantes del área. El financiamiento ha tenido fuentes tanto locales como internacionales, tales como el Centro Internacional de Física Teórica (ICTP), en Trieste, Italia; la Agencia Interamericana para la Investigación del Cambio Global (IAI); el Centro Latinoamericano de Física (CLAF); la Sociedad Americana de Óptica (OSA) y la Agencia Espacial Europea (ESA). Se elaboró un Reporte sobre los principales logros de este taller así como los nuevos retos que se plantean para los próximos talleres.

En el marco de este taller se reconoció la labor realizada durante toda la vida por el Dr. Barclay Robert Clemesha, quien desde el mismo surgimiento de la técnica lidar, inició sus trabajos en el tema.

Importantes sugerencias fueron hechas en el curso de la sesión de discusión, tales como, la organización de una Escuela de Verano sobre Lidares en Latino América. Otra sugerencia de este taller fue adicionar dos páginas más al sitio existente sobre los talleres. Una página contendrá vínculos a la literatura sobre lidar más importante. El otro tendrá vínculos a oportunidades regionales e internacionales para becas en el área de lidares para graduados y estudiantes. Los participantes coincidieron que será crucial para la efectividad de estas páginas, que todo aquel con información relevante contribuya con la misma.

The eruption of the Soufrière Hills Volcano on the Caribbean island of Montserrat on May 20, 2006 was observed by two satellite borne instruments, CALIPSO and OMI. The CALIPSO instrument is a satellite-borne down-looking lidar that measures the backscatter from clouds and aerosols. The OMI instrument measures a number of gases, including total column SO₂. The OMI science team created a “realtime” movie showing a c...

Observing Aerosols and Clouds with CALIPSO

David Winker

NASA Langley Research Center

Global monitoring of aerosols is important not only because of aerosol effects on the Earth radiation budget but also because of potential impacts on air quality, cloud properties, and precipitation. The CALIPSO satellite is providing the first continuous observations of the global three-dimensional distribution of aerosols. CALIPSO was launched in April 2006 and has been acquiring lidar observations since early June 2006. The primary instrument on the CALIPSO satellite is CALIOP, a two-wavelength polarization lidar designed...

Lidars for Atmospheric Probing: A Review

Sohan L. Jain

Radio & Atmospheric Sciences Division Radio, National Physical Laboratory, New Delhi - 110 012, INDI

The earth’s environment is constantly changing. Human activities have been influencing the global atmosphere since the beginning of the industrial era, causing shifts from its natural state. For example, the release of chlorofluorocarbons has significantly increased the rate of destruction of protective ozone by influencing chemical reactions in the polar stratosphere. Also the measurements have shown that tropospheric ozone is increasing grad...

The early history of atmospheric lidar

Barclay Robert Clemesha

Instituto Nacional de Pesquisas Espaciais

Although the history of atmospheric lidar starts in the early 60s, the history of optical radar for atmospheric studies is much older. The first suggestion that the scattering of light by atmospheric molecules could be used to measure the vertical profile of atmospheric density appears to have been made by Synge (1930), and the first attempt to implement the technique was made by Hulbert (1939) who was able to measure the light scattere...
