RISTiming Uncertainty of the Lightning Imaging Sensor
Publisher: American Meteorological Society
Abstract: he timing uncertainty of the Lightning Imaging Sensor (LIS), on orbit, is not currently accurately known. This is due to an imprecise value of the frame rate in the literature; the conceptual design value of 500 frames per ...
A Comparison of the Optical Pulse Characteristics of Intracloud and Cloud-to-Ground Lightning as Observed above Clouds
Publisher: American Meteorological Society
Abstract: The time-resolved optical waveforms at 777.4 nm and electric-field changes produced by intracloud and cloud-to-ground lightning flashes were measured above clouds from a U2 airplane (flying at a height of 20 km) at the ...
A Bayesian Approach to Assess the Performance of Lightning Detection Systems
Publisher: American Meteorological Society
Abstract: istorically, researchers explore the effectiveness of one lightning detection system with respect to another system; that is, the probability that system A detects a discharge given that system B detected the same discharge ...
Where Are the Lightning Hotspots on Earth?
Publisher: American Meteorological Society
Abstract: revious total lightning climatology studies using Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensor (LIS) observations were reported at coarse resolution (0.5°) and employed significant spatial and temporal ...
Combined Satellite- and Surface-Based Estimation of the Intracloud–Cloud-to-Ground Lightning Ratio over the Continental United States
Publisher: American Meteorological Society
Abstract: Four years of observations from the NASA Optical Transient Detector and Global Atmospherics National Lightning Detection Network are combined to determine the geographic distribution of the climatological intracloud?clou ...
Vertical Development of Lightning Activity Observed by the LDAR System: Lightning Bubbles
Publisher: American Meteorological Society
Abstract: In some Florida thunderstorm cells, impulsive very high frequency (VHF) radiation from lightning channels begins abruptly in a layer that is typically 3?6 km in diameter, 1?3 km tall, and initially located just above the ...
Laboratory Calibration of the Optical Transient Detector and the Lightning Imaging Sensor
Publisher: American Meteorological Society
Abstract: The authors present in detail the laboratory apparatus and techniques that were used to complete a full radiometric calibration of two space-based lightning detectors: the optical transient detector (OTD) and the lightning ...
Some Scientific Objectives of a Satellite-Borne Lightning Mapper
Publisher: American Meteorological Society
Abstract: The Lightning Mapper Sensor is proposed as an instrument for use on a geosynchronous satellite in the late 1980s to monitor lightning activity continuously over broad areas of the earth. The system was suggested in response ...
CHASER: An Innovative Satellite Mission Concept to Measure the Effects of Aerosols on Clouds and Climate
Publisher: American Meteorological Society
Abstract: tion of cloud droplets on aerosol particles, technically known as the activation of cloud condensation nuclei (CCN), is the fundamental process driving the interactions of aerosols with clouds and precipitation. The ...
