HMI ring diagram analysis II. Data products

Abstract

The combination of high resolution, spatial coverage, and continuity of photospheric Doppler and other data from HMI has allowed us to embark on a program of systematic exploration of solar subsurface flows and thermal structure variations using the technique of ring-diagram analysis on an unprecedented scale. There are two ring-diagrams pipelines, as described in [1]. In this paper we discuss the synoptic pipeline execution and describe the data being processed and produced. © Published under licence by IOP Publishing Ltd.
