A simple, yet efficient and fairly accurate algorithm is presented to estimate photosynthetically available radiation (PAR) at the ocean surface from Global Imager (GLI) data. The algorithm utilizes plane-parallel radiation-transfer theory and separates the effects of the clear atmosphere and clouds, i.e., the planetary atmosphere is modeled as a clear atmosphere positioned above a cloud layer....

introduction: air temperature as an important climatic factor can influence variability and distribution of other climatic parameters. therefore, tracking the changes in air temperature is a popular procedure in climate change studies.. according to the national academy in the last decade, global temperature has raised 0.4 to 0.8⁰c. instrumental records show that, with the exception of 1998, th...

A coupled Bayesian model selection and geostatistical regression modeling approach is adopted for empirical analysis of gross primary productivity (GPP) at six AmeriFlux sites, including the Kennedy Space Center Scrub Oak, Vaira Ranch, Tonzi Ranch, Blodgett Forest, Morgan Monroe State Forest, and Harvard Forest sites. The analysis is performed at a continuum of temporal scales ranging from dail...

UNLABELLED Compliance and persistence with daily, weekly, and monthly bisphosphonates (BPs) for osteoporosis were assessed using data from the Platform for Clinical Information Statistical Analysis (CISA) database that contains data of prescriptions in 13 university hospitals in Japan. The analysis revealed compliance and persistence improved as the dosing interval increases. PURPOSE BPs are ...

Abstract. The complementary principle has been widely used to estimate evaporation under different conditions. However, it remains unclear at which timescale the performs best. In this study, estimations were conducted 88 eddy covariance (EC) monitoring sites multiple timescales (daily, weekly, monthly, and yearly) by using sigmoid polynomial generalized functions. results indicate that functio...

In order to assess the impact of natural and anthropogenic stresses on forest ecosystems, it is necessary to interpolate air temperature and tropospheric ozone (O3) exposure values at high spatial resolution over complex terrain. The proposed interpolation approach was selected because of its ability to (1) account for the effect of elevation on temperature and their effects on tropospheric ozo...
