The validation of the Sea Surface Temperature (SST) estimated from images of the MODIS and VIIRS sensors has been carried out, for the study area delimited between the longitudes of 83o - 80oW and latitudes of 3o - 7oS respectively, in the period from 2001 to 2016 with data from the SST in-situ. Likewise, the monthly average data of the Concentration of Chlorophyll-a (CCA) and TSM VIIRS for the Sechura Bay, in the period from 2012 to 2018, have been related. The in-situ data of TSM are registered by IMARPE, (2000 - 2015). The daily and monthly CCA and TSM images for the study area are obtained from the Ocean Color portal. SeaDAS version 7.5.3 image processing software has been used on Linux Ubuntu 16.04 with netcdf format. The monthly averages of SST-MODIS and the in-situ SST at the Paita station present a correlation coefficient R = 0.96, so we can propose its use in models of oceanogra...

The purpose of this study is to implement the OC2 and OC3 algorithms to estimate the concentration of surface chlorophyll-a (CCA) from image data from the OLI sensor aboard the Landsat-8 satellite. The LaSRC (Landsat 8 Surface Reflectance Code) atmospheric correction model was validated with on-site measurements of the reflectance of the water surface recorded with a spectroradiometer on the surface of the fan shell crop area of the Sechura Bay. Validation results in a linear correlation coefficient of R = 95.1 % and a mean square error RMSE = 0.0095. A comparison of the CCA derived from the OC2 and OC3 algorithms was also made, resulting in an RMSE = 0.145 mg/m3 and a correlation coecient of R = 99 %. Finally, a contrast was made of the histograms of the spatial distribution of the CCA estimated from the OC2 and OC3 algorithms over a region of the study area. The results indicate a grea...

a presente investigación denominada PERCEPCIÓN DE LA CALIDAD DE SERVICIO EDUCATIVO UNIVERSITARIO Y SU RELACIÓN CON LA PREFERENCIA DE LOS ESTUDIANTES DEL 5TO AÑO DEL NIVEL SECUNDARIO DE LA CIUDAD DE TARAPOTO, tiene por objetivo determinar la relación entre la percepción de la calidad de servicio educativo universitario y la preferencia de los estudiantes del 5to año del nivel secundario de la ciudad de Tarapoto. En la investigación se trabajó con un diseño descriptivo y correlacional y un estudio de tipo no experimental, en donde se trabajó con un muestra poblacional de 308 estudiantes del 5to año del nivel secundario de la ciudad de Tarapoto a quienes se les aplico un cuestionario de preguntar para conocer el nivel de percepción de la calidad de servicio educativo universitario y las preferencias de estos estudiantes con respecto a esta percepción. En la investigación desp...
