Records of nitrate(NO-3),which is a nitrogenous inorganic ion with the highest concentration in snow and ice,are one important aspect of studies in global change.In recent years,a series of research on nitrate records was implemented in Polar Regions and mid/low latitude regions with high altitude,while the environmental significant of nitrate were reported.The latest progress of nitrate concentration records in snow and ice have been reviewed in aspects of possible sources,temporal-spatial variation characteristics,atmosphere-snow-ice transformation process and so on.The sources of nitrate in snow and ice can be subdivided into natural sources(e.g.solar activities,continental dust,lightning,cosmic events,aurora australis,supernova,volcanic eruption,biomass burning,nuclear test,etc.),and anthropogenic sources.The temporal-spatial variation of nitrate concentration is displayed basically on seasonal and annual variations temporally and elevation variation and variation with maritime-continent relation spatially.Additionally,the prospect was also discussed in this review.More attention should be paid in the future on combination of stationary observation and unfixed observation,microcosmic measurements of nitrate concentration on the interfaces of atmosphere-snow and sow-ice and spatial comparisons of nitrate concentration on continental and global scales.
