Relativistic microburst storm characteristics: Combined satellite and ground-based observations

Planet Sensitivity from Combined Ground- and Space-based Microlensing Observations

To move one step forward toward a Galactic distribution of planets, we present the first planet sensitivity analysis for microlensing events with simultaneous observations from space and the ground. We present this analysis for two such events, OGLE-2014-BLG-0939 and OGLE-2014-BLG-0124, which both show substantial planet sensitivity even though neither of them reached high magnification. This s...

Aerosol Optical Properties of a Haze Episode in Wuhan Based on Ground-Based and Satellite Observations

A severe haze episode that occurred in Wuhan, central China, from 6–14 June 2012 was investigated using ground-based and satellite-derived observations, from which the optical properties and vertical distribution of the aerosols were obtained. The mass concentrations of PM2.5 and black carbon (BC) were 9.9 (332.79 versus 33.66 μg·m) and 3.2 times (9.67 versus 2.99 μg·m) greater, respectively, o...

Estimating Winter Annual Biomass in the Sonoran and Mojave Deserts with Satellite- and Ground-Based Observations

Winter annual plants in southwestern North America influence fire regimes, provide forage, and help prevent erosion. Exotic annuals may also threaten native species. Monitoring winter annuals is difficult because of their ephemeral nature, making the development of a satellite monitoring tool valuable. We mapped winter annual aboveground biomass in the Desert Southwest from satellite observatio...

Investigation of lonotphmc perturbation due to Seismic activity using satellite and ground based observations

There is some intriguing research about whether large magnitude earthquakes are associated with ionospheric changes caused by electromagnetic signals released by the crushing of rock and their crystalline structures. If so then ionospheric changes might be a mechanism for major earthquake prediction. Prior to some recent quakes, scientists have detected electromagnetic and other disturbances in...
