The Solar Radiation Physical Modeling (SRPM) project is a computing system for quantitative evaluation of physical processes
modeling in the context of high spectral resolution solar observations. The forward-computation modular design is based on a
set of components that permit the researcher to compute the high-resolution spectrum of the solar atmosphere at any
wavelength based on given physical processes and parameters. The SRPM object-oriented design allows for either internally
computing or using externally generated parameters (e.g., atmospheric models, level populations, etc.) and computing very
detailed radiative losses and emitted spectrum. The computed data and the input atomic data are stored in relations databases
that are accessed via SQL. The atomic data is often updated with the latest from NIST, TOPBASE, CHIANTI, etc.
Current modules include: H and other elements NLTE with PRD calculations, computation of coronal loop footpoints transition
region energy balance and H particle diffusion, and computation of the entire solar spectrum for 1-dimensional models with
either LTE or provided ionization and level populations. A set of semi-empirical 1-dimensional models is being developed for
quiet and active solar features to fit much of the observed spectra.
New modules and algorithms under construction are 3-dimensional NLTE radiative transfer for chromospheric and prominence
applications, convection-diffusion equation for studying flows and particle diffusion in coronal loops and their footpoints,
and MHD simulation coupled with the NLTE radiative-transfer.
