Correction of Tropical Rainfall Measuring Missions Satellite Data of Solar Radiation for the High Andean Areas of Peru

The spatial and temporal quantification of climatic elements is necessary in different regions of the world, as mitigation policies against climate change in recent years the use of renewable energies has been promoted, with solar radiation being an important element, the objective is to correct Tropical Rainfall Measuring Missions (TRMM) satellite data series of solar radiation with respect to the data observed through an automatic meteorological station for a short period at a point located in the southern Peruvian Andes, we proceeded to process the observed data and download satellite information, making use of From a mathematical model, the correction coefficients of the satellite data were determined; The multiplicative factor model better corrects the satellite information, the Pearson correlation improved from R = 0.65 to R = 0.84 for monthly solar radiation, in the series of satellite data corrected for 37 years, a trend was determined -0.0006 Watt/m2/month.

Role of Geoinformation Expert System in Tasks of Interpretation of Aerospace Information

The article deals with the problem of increasing the efficiency of processing and interpretation of aerospace information. For this purpose, it is proposed to use artificial intelligence methods such as pattern recognition, neural expert systems, geoinformation technologies. Using the example of constructing a geoinformation expert system for assessing the suitability of lands, a method is shown for integrating a set of data and technologies to reduce time and increase the reliability of interpretation of the results of processing satellite information.
