Evaluating the agreement between measurements and models of net ecosystem exchange at different times and timescales using wavelet coherence: an example using data from the North American Carbon Program Site-Level Interim Synthesis
Earth system processes exhibit complex patterns across time, as do the models that seek to replicate these processes. Model output may or may not be significantly related to observations at different times and on different frequencies. Conventional model diagnostics provide an aggregate view of model–data agreement, but usually do not identify the time and frequency patterns of model–data disag...
متن کاملTerrestrial biosphere models need better representation of vegetation phenology: results from the North American Carbon Program Site Synthesis
Phenology, by controlling the seasonal activity of vegetation on the land surface, plays a fundamental role in regulating photosynthesis and other ecosystem processes, as well as competitive interactions and feedbacks to the climate system. We conducted an analysis to evaluate the representation of phenology, and the associated seasonality of ecosystem-scale CO2 exchange, in 14 models participa...
متن کاملA Micromorphological Analysis of the Neolithic site of Mahtaj, Behbahan Plain
One of the long-lasting discussions concerning early Neolithic sites in the Iranian plateau deals with the issue of seasonal or permanent settlements that is directly related to level of human mobility during this period. It is noteworthy that this time period coincided with earliest signs of sedentary life style and domestication of some species of animal and plants. What kinds of activities w...
متن کاملCharacterizing Reservation Management for Media Gateway Controller (Performance and Reliability)
In this paper, analysis and simulation of Media Gateway Controller (MEGACO) based COPS (Common Open Policy Server) which is a protocol defined in IETF (Internet Engineering Task Force) to transport configuration requests and deliver the policies is presented. For this scenario, three queuing models include M/M/1, M/M/c and M/D/c were applied . Then, some of the key performance benchmarks look l...
