Sentences with phrase «surface currents analysis»

Worldwide networks of buoys along with programs such as OSCAR (Ocean Surface Currents Analysis Real - time), which calculates surface currents based on satellite measurements, provide scientists with data on which to build and test their models.

From Yan Xue of NCEP The OSCAR object surface current analysis is regarded as a good current product, which we use to validate the GODAS current: http://www.oscar.noaa.gov/

For the study, Gentine and Lemordant took Earth system models with decoupled surface (vegetation physiology) and atmospheric (radiative) CO2 responses and used a multi-model statistical analysis from CMIP5, the most current set of coordinated climate model experiments set up as an international cooperation project for the International Panel on Climate Change.

NASA GISS Surface Temperature Analysis (GISSTEMP) describes how NASA handles the urban heat effect and links to current data.

an assessment of the current performance of the national surface transportation system and an analysis of the system's ability to achieve the policy, objectives, and goals set forth in sections 303 and 312;

But this is in a period that the Bureau has predicted is likely, based on statistical analysis of historical data and current sea surface conditions, to be warmer than the historical average (see here.

Detailed analysis of the results suggests that year - round surface emissions of CO, probably from fossil fuel burning in East Asia, and seasonal biomass burning emissions in South - central Africa, are greatly underestimated in current inventories used to drive models.

The motivation for this paper is twofold: first, we validate the model's performance in the Gulf of Mexico by comparing the model fields to past and recent observations, and second, given the good agreement with the observed Gulf of Mexico surface circulation and Loop Current variability, we expand the discussion and analysis of the model circulation to areas that have not been extensively observed / analyzed, such as the vertical structure of the Loop Current and associated eddies, especially the deep circulation below 1500 m.

Correlation analysis shows that dynamical forcing (wind or surface currents) is at least of the same order of importance as thermodynamical forcing for the ice extent variability in the Laptev, East Siberian, and Chukchi Seas.»

The results of this analysis indicate that observed temperature after 1998 is consistent with the current understanding of the relationship among global surface temperature, internal variability, and radiative forcing, which includes anthropogenic factors that have well known warming and cooling effects.

[2] The current GISS analysis employs NOAA ERSST.v5 for sea surface temperature, GHCN.v.3.3.0 for meteorological stations, and Antarctic research station data, as described in reference 1.

NASA GISS Surface Temperature Analysis (GISSTEMP) describes how NASA handles the urban heat effect and links to current data.

With regard to proxy studies, same basic questions, are these direct or passive correlations, what evidence that tree ring core thickness depends only on temperature (what about precipitation, cloud cover, volcanic activity, sea surface temperatue changes, sea current changes, solar irradiance changes, cloud cover, etc.) How are these variables accounted for when analysis of ice cores is completed, or for that matter when computer models, and / or proxy studies are completed.

Although the science of regional climate projections has progressed significantly since last IPCC report, slight displacement in circulation characteristics, systematic errors in energy / moisture transport, coarse representation of ocean currents / processes, crude parameterisation of sub-grid - and land surface processes, and overly simplified topography used in present - day climate models, make accurate and detailed analysis difficult.

In other words, their current analysis uses sea surface temperature data and they present two different datasets.
