Perched next to a river near a glacier’s edge in Greenland, Penn biogeochemist Jon Hawkings and Jack Murphy, senior research coordinator in Hawkings’ lab, scooped up samples of frigid meltwater, caref...
由于化石燃料燃烧,大气中二氧化碳(CO2)浓度的增加是全球变暖的主要驱动因素。卫星观测提供连续的全球 CO2反演产品,揭示大气CO2浓度的空间分布特征。然而,气候变化模拟研究大多是基于全球平均或纬向平均的大气CO2浓度假设。
A new approach to analyse satellite measurements of Earth's cloud cover reveals that clouds are very likely to enhance global heating.
In 2017, operational models predicted that Hurricane Harvey would become a Category 1 hurricane. Instead, it became a massive Category 4 storm just before it made landfall, and tied Hurricane Katrina ...
In the present study, a physics based method called Scheme for Atmospheric Correction of Landsat-8 (SACLS8) is developed for the Operational Land Imager (OLI) sensor of Landsat-8. The Second Simulatio...
The Himalayas have been widely accepted as one of the most sensitive indicators of climate change. However, the rugged terrains of the Indian Himalayas render it impossible to carry out ground based s...
Interferometric synthetic aperture radar(InSAR), as a space geodetictechnology, had been testified a high potential means of earth observation providing a method fordigital elevation model (DEM) and s...
The advanced very high resolution radiometer (AVHRR) data from the National Oceanic and Atmospheric Administration satellite is one of the earliest data applied in aerosol research. The dense dark veg...
The purpose of this study is to create a new dataset of spatially interpolated monthly climate data for South Korea at high spatial resolution (approximately 30m) by performing various spatio-statisti...
In recent years, the air pollution is becoming more and more serious, which not only causes the decrease of the visibility, but also affects the human health. As the most important pollutant particula...
Big data and data mining have provided several breakthroughs in fields such as health informatics, smart cities and marketing. The same techniques, however, have not delivered consistent key findings ...
Some great ideas are born out of years of painstaking research. Others are gleaned from the plotline of the movie "Twister."The latter is how Paul Markowski, professor of meteorology, and Yvette Richa...
A group of international scientists led by a climate expert from USC has upgraded an open-source global database tracking the Earth’s temperatures since 1 A.D. that further confirms the Earth is warmi...
Every year, severe weather endangers millions of people and causes billions of dollars in damage worldwide. But new research from Penn State’s College of Information Sciences and Technology (IST) and ...
The year 2016 is on pace to be the hottest on record, with each of the first six months setting new temperature records, according to NASA. Climate change, combined with the effects of El Niño, i...
