JULY 1960 MONTHLY WEATHER REVIEW 251 EXTRAPOLATION TO THE 50-MB. LEVEL IN ANTARCTICA* FROM 100-MB. DATA
Wint,er-month data obtained at United States Antarctic stations during the ICY are used to compute coefficients for regression equations relating the 100-mb. temperatures and heights to the 50-mb. heights. It is found upon trial that the layer thickness can be estimated as accurately from the 100-mb...
