Reference evapotranspiration based on class A pan evaporation

Scientia Agricola, 2002
Estimating reference evapotranspiration (ETo) based on Class A pan evaporation (ECA) is very usual in irrigated areas. For this purpose the ECA values are multiplied by a pan coefficient (Kp) to obtain ETo.

Spatial Patterns and Influence Factors of Conversion Coefficients between Two Typical Pan Evaporimeters in China [PDF]

Water, 2016
Pan measurement is a reliable and efficient method for indicating the evaporative demand of the atmosphere. There are several types of pan evaporimeters worldwide, and the estimation of the conversion coefficients (Kp) between them is necessary in hydrologic research. In China, E601B pans were installed at all meteorological stations beginning in 1998.

A combinatorial identity with application to Catalan numbers

, 2005
By a very simple argument, we prove that if $l,m,n$ are nonnegative integers then $$\sum_{k=0}^l(-1)^{m-k}\binom{l}{k}\binom{m-k}{n}\binom{2k}{k-2l+m} =\sum_{k=0}^l\binom{l}{k}\binom{2k}{n}\binom{n-l}{m+n-3k-l}.

The Relationship between Unemployment and Output Cycles in Korea [PDF]

This paper** addresses the problem of Okun's coefficient for the Korean economy. By running regressions between the unemployment and employment variables cycles and the economic activity cycles, I find that Okun's Law has held in Korea in the last ...
