Reliablemicrostructuremeasurement of snow is a requirement for microwave radiative transfer model *** specific surface area(SSA)can be measured using stereological methods,in which snow samples are cast in the field and photographed in the *** stereology photographs manually by counting intersections of test cycloids with air-ice boundaries reduces the problems in binary *** paper is a case study to evaluate the repeatability of the manually stereology interpretation by two independent research *** further assessed how uncertainty in snow SSA influences simulated brightness temperature(TB)driven by the Microwave Emission Model of Layered Snowpacks(MEMLS),and how stereology compares to Near Infrared(NIR)camera and hand *** was obtained from two alpine snow profiles from Steamboat Springs,*** showed that stereological SSA values measured by two groups are highly consistent,and the ground radiometer measured T_(B)at 19 and 37 GHz was successfully predicted(RMSEze(Dg)measurements have larger *** conclusion was not sensitive to uncertainty in the free parameters of TB modeling.
