TL;DR: The NASA Soil Moisture Active Passive (SMAP) mission has utilized a set of core validation sites as the primary methodology in assessing the soil moisture retrieval algorithm performance as mentioned in this paper.

TL;DR: The authors used complementary observations from the prototype and expanded Global Muon Detector Network (GMDN) and the Advanced Composition Explorer (ACE) satellite to identify precursors of geomagnetic storm events.

TL;DR: In this paper, the authors analyzed the effect of atmospheric effects on the Global Muon Detector Network (GMDN) and found that the seasonal temperature variation observed at the ground and at the altitude of maximum muon production are in antiphase for all GMDN locations (low-latitude regions).

TL;DR: In this article, a weak loss-cone (LC) signature is first recorded more than a day prior to the storm sudden commencement (SSC) onset, which suggests that the LC precursor appeared only 7 hours after the coronal mass ejection eruption from the Sun, when the interplanetary (IP) shock driven by the inter-planetary coronal maximum mass ejections was located at 0.4 AU from the sun.

TL;DR: The Global Muon Detector Network (GMDN) as discussed by the authors has a total of 60 directional channels with an improved coverage of the sunward Interplanetary Magnetic Field (IMF) orientation, making it possible to continuously monitor cosmic ray precursors of geomagnetic storms.
