To extend and reinforce the action of the European network EARLINET (supported by the EARLINET-ASOS European project), a network of Spanish and Portuguese aerosol lidars (SPALINET) was created. In the first three years of the project six out of the ten systems have been successfully intercompared, seven elastic algorithms and six Raman algorithms have also… (More)
In this study, estimated data of the UV Index on vertical planes are presented for the latitude of Valencia, Spain. For that purpose, the UVER values have been generated on vertical planes by means of four different geometrical models a) isotropic, b) Perez, c) Gueymard, d) Muneer, based on values of the global horizontal UVER and the diffuse horizontal… (More)
Values of measured and modeled diffuse UV erythemal irradiance (UVER) for all sky conditions are compared on planes inclined at 40 degrees and oriented north, south, east and west. The models used for simulating diffuse UVER are of the geometric-type, mainly the Isotropic, Klucher, Hay, Muneer, Reindl and Schauberger models. To analyze the precision of the… (More)
To extend and reinforce the action of the EARLINET-ASOS project, a network of Spanish advanced lidars was created. Six systems were intercompared satisfactorily in terms of signal similarity and backscatter coefficients.
—The Surface Processes and Ecosystem Changes Through Response Analysis (SPECTRA) Barrax Campaigns were validation campaigns developed in the framework of the SPECTRA mission in order to verify that the geophysical data products provided by satellite imagery are consistent with the measurements made by independent means. Two campaigns took place in Barrax,… (More)
