MOLECULAR HYDROGEN LINE IDENTIFICATIONS IN SOLAR FLARES OBSERVED BY IRIS: LOWER ATMOSPHERIC STRUCTURE FROM RADIOMETRIC ANALYSIS

Molecular Hydrogen Line Identifications in Solar Flares Observed by IRIS: Lower Atmospheric Structure from Radiometric Analysis

A rich spectrum of molecular hydrogen (H _2 ) emission lines is seen in sensitive observations from the far-ultraviolet (FUV) channels of the Interface Region Imaging Spectrograph (IRIS) during flare activity in solar active region NOAA Active Region 11861.Based on this observation, we have determined 37 new line identifications by comparing synthe

Comparison of calibration characteristics of different acoustic impact systems for measuring bedload transport in mountain streams

The Swiss plate geophone (SPG) system has been installed and tested in more than 20 steep gravel-bed streams and rivers, and related studies generally resulted in rather robust calibration relations between signal impulse counts and transported bedload mass.Here, we compare this system with three alternative surrogate measuring systems.A variant Bi
