ON METEORS AND RAINFALL

Journal of Meteorology, 1956
Abstract The correlations of heavy rainfall and of noctilucent clouds with meteor streams are examined with regard to the known facts of meteor astronomy. Photographic and radar observations show that the general influx of sporadic meteors is not greatly enhanced by the occurrence of a meteor stream, and it is unlikely that meteors within the present ...

Exogenous carbonaceous material on Phobos

Astronomy & Astrophysics
Aims. We analyze Mars Express (MeX)/OMEGA Phobos’ data in the 2.5–3.9 μm range to investigate the presence of organic material. Methods. We applied a thermal correction to the OMEGA data and identified regions of interest (ROIs) to extract mean spectra ...

Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...
