Emergence of Internetwork Magnetic Fields through the Solar Atmosphere

IRIS is a NASA Small Explorer Mission developed and operated by LMSAL with mission operations executed at NASA Ames Research Center and major contributions to downlink communications funded by the ESA and the Norwegian Space Centre. M.G., B.D.P., and A.S.D. are supported by NASA contract NNG09FA40C (IRIS). The work of L.B.R. and S.E.P. was supported by the Spanish Ministerio de Economia and Competitividad through grants ESP201347349-C6-1-R and ESP2016-77548-C5-1-R, including a percentage from European Regional Development Fund (FEDER) funds. L.B.R. acknowledges financial support from the State Agency for Research of the Spanish Ministerio de Ciencia e Innovacion through project RTI2018-096886-B-C5 (including FEDER funds) and through the "Center of Excellence Severo Ochoa" award to the Instituto de Astrofisica de Andalucia (SEV-2017-0709). The Swedish 1 m Solar Telescope is operated on the island of La Palma by the Institute for Solar Physics of Stockholm University in the Spanish Observatory del Roque de los Muchachos of the Instituto de Astrofisica de Canarias. The Institute for Solar Physics is supported by a grant for research infrastructures of national importance from the Swedish Research Council (registration No. 2017-00625). This research has made use of NASA's Astrophysics Data System.
