Surya is an open‑source, AI‑based foundation model for heliophysics developed collaboratively by NASA (via the IMPACT AI team) and IBM. Named after the Sanskrit word for “sun,” Surya is trained on nine years of high‑resolution solar imagery from NASA’s Solar Dynamics Observatory (SDO). It is designed to forecast solar phenomena—such as flares, solar wind, irradiance, and active region behavior—by predicting future solar images with a sophisticated long–short vision transformer architecture, thereby enabling improved space weather forecasting. Foresees solar flares, wind, EUV spectra, and active region formation in advance. ...

Fast FDTD solver with graphics card support. Optimized for nanoscale optics - scanning near field optical microscopy, rough surface scattering and solar cells. Uses CUDA environment for graphics card operation.

A package for transient and steady state simulation of organic solar cells.

...The intensities of these signals reflect the ability of radio waves at those wavelengths to propagate in what is essentially a waveguide formed by the earth and the ionosphere above it. Fluctuations in those signal intensities and directions often reflect daytime perturbations of the ionosphere by solar processes, such as solar flares and coronal mass ejections, making VLF receivers useful tools for probing the sun and the earth's ionosphere.

Cosmic ray electrons scatter on the photon fields around stars, including the sun, to create gamma rays by the inverse Compton effect. This program computes the spectrum and angular distribution of this emission. The software also includes general-purpose routines for inverse Compton scattering on a given electron spectrum, for example for interstellar or astrophysical source modelling. For further information see these publications: http://arxiv.org/abs/astro-ph/0607563,...

Programs to download and work with satellite measurements, calculate solar wind (SW) propagation time and compare data to other satellites. It uses and compares different modern techniques to determine the SW planar structures orientation.

SunThink! is an INRIA Scilab-based program that assists in the good design of solar electricity systems. Its primary purpose is to facilitate the accurate, appropriate sizing of these systems to fit the specific design goals that are held for them.

This is an application that computes the date and time in formats appropriate for astronomers - julian date, sidereal time, modified julian date, truncated julian date. Extremely accurate, includes correction for apparent sidereal time.
