  • Comparación del desempeño en la prueba Saber 11° 2022 entre colegios públicos y privados de Soacha

    Open AccessJorge Enrique Dí­az PinzónARTICLEEl Ágora USB2025

    El objetivo de esta investigación fue comparar si existen diferencias en el promedio de los puntajes obtenidos entre las variables del sector educativo (público y privado) y los puntajes en las pruebas de lectura crítica, matemáticas, sociales y ciudadanas, ciencias naturales, inglés y puntaje promedio de la prueba Saber 11°-2022 en el municipio de Soacha, Cundinamarca. Mediante una metodología cuantitativa, se analizaron los datos de los resulta…

  • Monitoreo de temperatura en el aula de clase basada en Arduino

    Open AccessJorge Enrique Dí­az Pinzón, Jorge Rodríguez GonzálezARTICLEEl Ágora USB2024

    En la Institución Educativa General Santander, ubicada en el municipio de Soacha, Cundinamarca, se diseñó e implementó una estación meteorológica portátil con sensor de temperatura para el aula de clase. El sistema, programado con Arduino, permitió a los usuarios obtener información meteorológica en tiempo real. Los datos recopilados revelaron que la temperatura en las aulas oscila entre 24°C y 29°C. La investigación, además de resumir las condic…

  • Climate drivers of Arctic tundra variability and change using an indicators framework

    Open AccessUma S Bhatt, Donald A Walker et al.ARTICLEEnvironmental Research Letters2021

    This study applies an indicators framework to investigate climate drivers of tundra vegetation trends and variability over the 1982–2019 period. Previously known indicators relevant for tundra productivity (summer warmth index (SWI), coastal spring sea-ice (SI) area, coastal summer open-water (OW)) and three additional indicators (continentality, summer precipitation, and the Arctic Dipole (AD): second mode of sea level pressure variability) are …

  • Changing seasonality of panarctic tundra vegetation in relationship to climatic variables

    Open AccessUma S Bhatt, Donald A Walker et al.ARTICLEEnvironmental Research Letters2017

    Potential climate drivers of Arctic tundra vegetation productivity are investigated to understand recent greening and browning trends documented by maximum normalized difference vegetation index (NDVI) (MaxNDVI) and time-integrated NDVI (TI-NDVI) for 1982–2015. Over this period, summer sea ice has continued to decline while oceanic heat content has increased. The increases in summer warmth index (SWI) and NDVI have not been uniform over the satel…

  • A Non-Stationary 1981–2012 AVHRR NDVI3g Time Series

    Open AccessJorge Enrique Dí­az Pinzón, Jorge Pinzon et al.ARTICLERemote Sensing2014

    The NDVI3g time series is an improved 8-km normalized difference vegetation index (NDVI) data set produced from Advanced Very High Resolution Radiometer (AVHRR) instruments that extends from 1981 to the present. The AVHRR instruments have flown or are flying on fourteen polar-orbiting meteorological satellites operated by the National Oceanic and Atmospheric Administration (NOAA) and are currently flying on two European Organization for the Explo…

  • Dynamics of aboveground phytomass of the circumpolar Arctic tundra during the past three decades

    Open AccessHoward E Epstein, Martha K Raynolds et al.ARTICLEEnvironmental Research Letters2012

    Numerous studies have evaluated the dynamics of Arctic tundra vegetation throughout the past few decades, using remotely sensed proxies of vegetation, such as the normalized difference vegetation index (NDVI). While extremely useful, these coarse-scale satellite-derived measurements give us minimal information with regard to how these changes are being expressed on the ground, in terms of tundra structure and function. In this analysis, we used a…

  • Recent change of vegetation growth trend in China

    Open AccessShushi Peng, Anping Chen et al.ARTICLEEnvironmental Research Letters2011

    Using satellite-derived normalized difference vegetation index (NDVI) data, several previous studies have indicated that vegetation growth significantly increased in most areas of China during the period 1982–99. In this letter, we extended the study period to 2010. We found that at the national scale the growing season (April–October) NDVI significantly increased by 0.0007 yr −1 from 1982 to 2010, but the increasing trend in NDVI over the last d…

  • Circumpolar Arctic Tundra Vegetation Change Is Linked to Sea Ice Decline

    Uma S Bhatt, Donald A Walker et al.ARTICLEEarth Interactions2010

    Linkages between diminishing Arctic sea ice and changes in Arctic terrestrial ecosystems have not been previously demonstrated. Here, the authors use a newly available Arctic Normalized Difference Vegetation Index (NDVI) dataset (a measure of vegetation photosynthetic capacity) to document coherent temporal relationships between near-coastal sea ice, summer tundra land surface temperatures, and vegetation productivity. The authors find that, duri…

  • An extended AVHRR 8‐km NDVI dataset compatible with Modis and SPOT vegetation NDVI data

    Compton J Tucker, Jorge Enrique Dí­az Pinzón et al.ARTICLEInternational Journal of Remote…2005

    Daily daytime Advanced Very High Resolution Radiometer (AVHRR) 4‐km global area coverage data have been processed to produce a Normalized Difference Vegetation Index (NDVI) 8‐km equal‐area dataset from July 1981 through December 2004 for all continents except Antarctica. New features of this dataset include bimonthly composites, NOAA‐9 descending node data from August 1994 to January 1995, volcanic stratospheric aerosol correction for 1982–1984 a…
