Influencia de la temperatura en las medidas de irradiancia espectral
Las técnicas radiométricas se han empleado durante muchos años para obtener propiedades ópticas de los aerosoles en la columna atmosférica. Habitualmente los espectrorradiómetros y fotómetros permanecen en el exterior, sobre seguidores automáticos, que permiten la medida de la radiación solar directa a lo largo de todo el día. Estos instrumentos se ven afectados por la temperatura ambiente, por lo que es preciso determinar su efecto para corregir las medidas de irradiancia. For many years the radiometric techniques have been widely applied for retrieving several aerosol optical properties in the atmospheric column. Usually the spectroradiometers are deployed outdoors on automatic sun tracki…
A new approach for characterizing atmospheric aerosols from spectral values of their optical depth. A simulated case study.
We are developing a new method to determine the spectral contribution to the aerosol optical depth due to each aerosol type. An aerosol type depends directly on the procedence of the particles (marine, continental, artic, etc) and it is formed by some different pure components (mineral, soot, soluble and insoluble particles, sulphate, etc). In order to separate these contributions it is necessary to have the spectral aerosol optical thickness and aerosol size distribution. We use this distribution function to identify the different components of aerosols allowing us to reconstruct the aerosol optical depth taking into account the contribution of each type of aerosol. The validation of the m…
