We describe the results of the study of aerosol optical depth (AOD) and Direct Radiative Forcing (DRF) at the top of the atmosphere (TOA), obtained in the period 2004 using the MODIS sensor of the TERRA satellite for Peru. Where it is observed that the AOD value can take maximum values around 0.5, resulting in aerosol DRF in the upper part of the atmosphere. The results indicate that the FRD is between [-5 0] W / m2.

Describimos los resultados del estudio del espesor óptico de aerosol (EOA) y el Forzamiento Radiativo Directo (FRD) en la cima de la atmósfera (TOA), obtenidos en el periodo 2004 utilizando el sensor MODIS del satélite TERRA para Perú. Donde se observa que el valor del EOA puede tomar valores máximos alrededor de 0.5, obteniéndose como resultado el FRD de aerosol en la parte superior de la atmósfera. Los resultados indican que, la FRD está entre [-5 0] W / m2.

In this work, the spatial dynamic behavior of the aerosol index for the department of Junín is exposed. The basic information for the development of this research is satellite data obtained from NASA. The AURA satellite that has the OMI sensor installed has been monitoring the aerosol index (AI) since October 2004-2018. The satellite observations are as a whole a historical series of the concentration of the index, the data also have geographic coordinate information, which is why it was used to evaluate and simulate the spatial behavior using Kriging's spatial interpolation methodology. Where the greatest amount of suspended particles is observed both in the dry and wet season in the urban area that belongs to the province of Huancayo.

The objective of this research is to determine the variation of the total ozone column over the regions of Huancayo, Santiago de Chile and Antarctica. The study focused on measurements of the total ozone column over Huancayo, Santiago de Chile and the Machupicchu Antarctic Research Station (ECAMP). Total column ozone data were obtained by NASA's Ozone Monitoring Instrument (OMI) over 16 years (2005-2020). Likewise, it was obtained that in Huancayo a monthly average of 243.1 Dobson Units (DU). In the Peruvian Antarctic station there is a monthly average of 276 DU. And, finally, the registered data obtained the minimum and maximum value of 237 (May) and 254 (September) respectively. Likewise, in Santiago de Chile the minimum and maximum value of 251 (March) and 301 (September) respectively were obtained. In Antarctica, the minimum and maximum value of 220 (September) and 310 (December) res...

La rápida urbanización de las ciudades está cambiando el clima local, lo que genera altas temperaturas y entornos urbanos densos y difíciles, carentes de agua y vegetación[1]. La presente contribución estima la intensidad de Isla de Calor Urbano Superficial (ICUS) durante el periodo 2001 – 2022 para el Área Metropolitana de Huancayo (AMH), Perú. Se cuantificó formación de la Isla de Calor Urbano Superficial, a partir de 2 métodos: el primero es el método de Streutker, el cual ajusta la temperatura superficial del suelo (LST) (superficie urbana y rural) a una superficie Gaussiana. El segundo, método de cuantil propuesto por José Flores, usa la diferencia entre el cuantil 0.95 de LST del área urbana y la mediana del LST del área rural. Ambos métodos usan data de sensoramiento remoto de LST a 0.05⁰ de resolución, obtenido del sensor MODIS a bordo del satélite TERRA y ...

Por naturaleza el cielo no es totalmente limpio, sin embargo cuando la concentración de partículas es mayor a la normal puede atenuar con mayor intensidad la de radiación solar. Por lo que la cantidad de radiación solar que llega hasta la superficie terrestre depende en gran medida de la turbidez atmosférica. De esta manera, el objetivo de este trabajo fue estimar los valores óptimos diarios de la turbidez atmosférica y parámetros radiativos de superficie tales como: el coeficiente de turbidez de Angstrom (β), exponente de longitud de onda de Angstrom (α), el albedo de dispersión simple (ω₀) y dispersión ascendente (Fc). Mediante mediciones de radiación solar incidente (global, directa y difusa), realizadas entre junio y julio del 2019 en la Provincia de Huancayo-Perú, se realizó los cálculos de los parámetros antes presentados. El modelo numérico usado para calcular...

This work presents results of Aerosol Optical Depth (AOD) and Direct Radiative Force (DRF) at the top of the atmosphere (TOA), obtained during monitoring campaigns carried out at the Huancayo Observatory of the Geophysical Institute of Peru (OH-IGP ) in April and August 2022. In these campaigns, a Sun CIMEL photometer was used to measure the microphysical and optical properties of aerosols at wavelengths ranging from 340 to 1020 nm, and a low-cost Purple-air sensor to quantify the concentration of material particulate (PM), in fine and coarse modes. The AOD results indicated values in the range 0.06-0.22. The daily averages of PM2.5 and PM10 did not exceed Peru’s current Environmental Quality Standards (50 μg/m³ and 100 μg/m³). The air quality index (AQI) calculated for PM2.5 and PM10 was classified as good. On some days during the campaigns, the air quality was classified as moder...
