The spectral characteristics of E-region radar echoes co-located with and adjacent to visual auroral arcs [PDF]
Annales Geophysicae, 2002 Simultaneous all-sky camera and HF radar observations of the visual and E-region radar aurora in the west-ward electrojet suggest a close relationship between a pair of parallel east-west-aligned auroral arcs, separated by ~ 30 km, and a region of ...

Importance of seasonal and annual layers in controlling backscatter to radar altimeters across the percolation zone of an ice sheet [PDF]
, 2006 Radar altimeters are one of the main tools for measuring elevation changes across the Antarctic and Greenland ice sheets and larger ice caps. A ground-based radar was deployed in autumn 2004 and spring 2006 in the percolation zone of the Greenland Ice ...

Water stress detection in the Amazon using radar
Geophysical Research Letters, 2017 The Amazon rainforest plays an important role in the global water and carbon cycle, and though it is predicted to continue drying in the future, the effect of drought remains uncertain.

D region HF radar echoes associated with energetic particle precipitation and pulsating aurora [PDF]
, 2008 Milan et al. (2001) identified a class of narrow, slow-moving HF radar backscatter echoes which originate between altitudes of 80 and 100 km, the ionospheric D- and lower E-regions.
