Lightning Reporting at 45th Weather Squadron: Recent Improvements [PDF]

, 2010
The 45th Weather Squadron (45 WS) provides daily lightning reports to space launch customers at CCAFS/KSC. These reports are provided to assess the need to inspect the electronics of satellite payloads, space launch vehicles, and ground support equipment

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

Oikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.

Joint distribution of lightning and wind speed and its impact on the transmission system

Frontiers in Energy Research
Distribution of lightning plays a key role in lightning protection of transmission lines. The design of wind deviation under lightning overvoltage of the transmission tower is an empirical parameter in the transmission line design code.

A new population of terrestrial gamma-ray flashes in the RHESSI data [PDF]

, 2015
Terrestrial gamma-ray flashes (TGFs) are the most energetic photon phenomenon occurring naturally on Earth. An outstanding question is as follows: Are these flashes just a rare exotic phenomenon or are they an intrinsic part of lightning discharges and ...

Lightning Location and Peak Current Estimation From Lightning-Induced Voltages on Transmission Lines With a Machine Learning Approach

IEEE transactions on electromagnetic compatibility (Print)
In this article, a machine-learning-based model for the regression of cloud-to-ground lightning location and peak current from time-domain waveforms of lightning-induced voltage measurements on overhead transmission lines is presented.

Detecting and attributing climate change effects on vegetation: Australia as a test case

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Observations of ozone production in a dissipating tropical convective cell during TC4 [PDF]

, 2010
From 13 July–9 August 2007, 25 ozonesondes were launched from Las Tablas, Panama as part of the Tropical Composition, Cloud, and Climate Coupling (TC4) mission. On 5 August, a strong convective cell formed in the Gulf of Panama.
