Behind the curve: a comparison of historical sources for the Carnegie curve of the global atmospheric electric circuit [PDF]
History of Geo- and Space Sciences, 2020 The “Carnegie curve” describes the diurnal variation of the global atmospheric electric circuit. It was originally found from atmospheric electric potential gradient (PG) measurements made on the Carnegie, effectively a floating atmospheric electrical ...

Surveys in Geophysics, 2012 Abstract The Earth’s fair weather atmospheric electric field shows, in clean air, an average daily variation which follows universal time, globally independent of the measurement position. This single diurnal cycle variation (maximum around 19UT and minimum around 03UT) is widely known as the Carnegie curve, after the geophysical survey ...

Atmospheric Research, 2020 Abstract The study of the global atmospheric electric circuit is important to understand the climate system and this can be done by monitoring the atmospheric electric field worldwide. In this way, continuous measurements of atmospheric electric field are being recorded by the Atmospheric electric FIeld Network in South America (AFINSA).

Geophysical Research Letters, 2015 AbstractIn fair weather, a clear diurnal variation of atmospheric electric field (AEF), which is distinctly different from the global diurnal variation, i.e., Carnegie curve, was observed during the summer time (July and August) of the year 2010 and 2011 at the summit of Mount Fuji, Japan (3776 m in altitude).

Carnegie Supernova Project: kinky i-band light curves of Type Ia supernovae [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We present detailed investigation of a specific i-band light-curve feature in Type Ia supernovae (SNe Ia) using the rapid cadence and high signal-to-noise ratio light curves obtained by the Carnegie Supernova Project. The feature is present in most SNe Ia and emerges a few days after the i-band maximum. It is an abrupt change in

Type II supernovae from the Carnegie Supernova Project-I [PDF]
Astronomy & Astrophysics, 2022 The present study is the first of a series of three papers where we characterise the type II supernovae (SNe II) from the Carnegie Supernova Project-I to understand their diversity in terms of progenitor and explosion properties. In this first paper, we present bolometric light curves of 74 SNe II. We outline our methodology to calculate the bolometric

Measuring Global Signals in the Potential Gradient at High Latitude Sites
Frontiers in Earth Science, 2021 Previous research has shown that the study of the global electrical circuit can be relevant to climate change studies, and this can be done through measurements of the potential gradient near the surface in fair weather conditions.

Comparison of the Atmospheric Electric Field from Three Global Stations in 2021
Universe, 2023 The atmospheric electric field is an important physical parameter used to study the state of charge density distribution between the earth and the ionosphere, and its daily variation characteristics reflect the underlying atmospheric electrical ...
