A model for the class A pan coefficient

Agricultural and Forest Meteorology, 1995
Abstract The class A pan coefficient ( K p ) has been found to be determined by the daily wind run ( WR ), the average relative humidity ( RH ), and the fetch distance ( FD ) of the pan. While it is quite easy to measure WR and RH , FD has to be estimated.

Evaporation Rate of a White Class A Evaporation Pan

Journal of Irrigation and Drainage Engineering, 2016
AbstractThis study experimentally investigates the influence of color on the evaporation rate of a Class A evaporation pan. Two Class A evaporation pans, one in the original galvanized metal color and the other painted white, are placed in the same meteorological station for 18 months.

Wind‐induced splash in Class A evaporation pan

Journal of Geophysical Research: Atmospheres, 2012
This study investigates the wind‐induced splash in the Class A evaporation pan through a series of wind tunnel experiments. The experimental results revealed that high wind speed can generate seiche wave inside the pan and splash water out of the pan in several minutes.

Automating a class a evaporation pan for semi-continuous recording

Agricultural Meteorology, 1981
Abstract Continuos monitoring of water loss from an evaporation pan was automated by using a system of 16 general-purpose Constantan wire-resistance strain gages mounted on four supporting arms. A change in pan weight from water loss proportionally changed the electrical resistance of the wire gages.

Differences in Evaporation Between a Floating Pan and Class A Pan on Land¹

JAWRA Journal of the American Water Resources Association, 2008
Abstract:  Research was conducted to develop a method for obtaining floating pan evaporation rates in a small (less than 10,000 m2) wetland, lagoon, or pond. Floating pan and land pan evaporation data were collected from March 1 to August 31, 2005, at a small natural wetland located in the alluvium of the Canadian River near Norman, Oklahoma, at the U ...

A Novel Class of Potent Nonglycosidic and Nonpeptidic Pan-Selectin Inhibitors

Journal of Medicinal Chemistry, 2006
An early step of the inflammatory response, the rolling of leukocytes on activated endothelial cells, is mediated by selectin/carbohydrate interactions. The tetrasaccharide sialy Lewisx is a ligand for E-, P-, and L-selectin and therefore serves as a lead structure for the development of analogues.

Evaporation from screened class a pans in a semi-arid climate

Agricultural Meteorology, 1983
Abstract Evaporation measurements from ‘screened’ and standard Class A pans at two locations near Fresno, California were compared together and with ‘potential evapotranspiration’ estimates, using two combination equations with climate data from the sites. The screen covering on a Class A pan reduced the Class A pan evaporation by 10%.

Time‐ and Level‐Controlled Filling System for Class A Evaporation Pans

Journal of Hydrologic Engineering, 1997
Recently developed integrated circuit technology and new reliable pressure transducers have made it possible to develop a battery-operated system to automatically fill class A evaporation pans from stored water. The system records and stores the average of 12 pan level records during a 1 min time period at the end of each every 15 min period for later ...

The heat balance of class A evaporation pan

Water Resources Research, 1966
The heat balance of a U.S. Weather Bureau class A evaporation pan located near Tucson, Arizona, was calculated for selected periods during the interval July 26–31, 1963. The method used required two pans, one of which was insulated on the side and bottom to prohibit heat transfer through these surfaces.
