A Feasibility Study of Photovoltaic—Electrolysis—PEM Hybrid System Integrated Into the Electric Grid System Over the Korean Peninsula

Frontiers in Chemistry, 2021
A photovoltaic–electrolysis–PEM hybrid model was developed for a feasibility study, and simulations of several scenarios in Korea were performed. The solar irradiance was derived from the University of Arizona solar irradiance based on satellite–Korea ...

Analyzing Regional and Local Changes in Irradiance during the 2019 Total Solar Eclipse in Chile, Using Field Observations and Analytical Modeling

Energies, 2021
Solar eclipses are astronomic phenomena in which the Earth’s moon transits between the planet and the Sun, projecting a shadow onto the planet’s surface.

Solar Irradiance Variability: Comparisons of Models and Measurements

Earth and Space Science, 2019
The Earth system responds to solar variability on a wide range of timescales. Knowledge of total solar irradiance (TSI) and solar spectral irradiance (SSI) spanning minutes to centuries is needed by scientists studying a broad array of research ...

Intercomparing Solar Spectral Irradiance From SORCE SIM

Earth and Space Science, 2020
We compare solar spectral irradiance (SSI) measurements obtained from the Spectral Irradiance Monitor (SIM) on board the Solar Radiation and Climate Experiment (SORCE), corrected for instrument degradation using three different methods; SIM Version 25 ...

Changes in the Total Solar Irradiance and climatic effects

Journal of Space Weather and Space Climate, 2021
The correlation between the averaged reconstructed March temperature record for Kyoto, Japan, and the reconstructed Total Solar Irradiance (TSI) over 660 years from 1230 to 1890 gives evidence with 98% probability that the Little Ice Age with four cold ...

Modelling solar irradiance from ground-based photometric observations

Journal of Space Weather and Space Climate, 2020
Total solar irradiance (TSI) has been monitored from space since 1978, i.e. for about four solar cycles. The measurements show a prominent variability in phase with the solar cycle, as well as fluctuations on timescales shorter than a few days.

Possible dependence between the total solar irradiance and dimethylsulphide [PDF]

Geofísica Internacional, 2009
Solar variability is one of the main natural influences on the Earth’s climate. Biological processes are profoundly affected by the solar irradiance. Some of these processes have been proposed to change the cloud albedo and therefore impact the climate ...

Overview of the NASA Solar Irradiance Science Team (SIST) Program Special Section

Earth and Space Science, 2019
Solar irradiance represents the dominant energy source heating the Earth's atmosphere and climate. Both total solar irradiance and spectral solar irradiance vary over the 11‐year solar cycle.

Solar Irradiance Variability: Modeling the Measurements

Earth and Space Science, 2020
New models of the Sun's irradiance variability are developed from 15 years of direct observations made by the Solar Radiation and Climate Experiment (SORCE) spacecraft from 2003 to 2017 (inclusive).
