Sentences with phrase «irradiance data from»

We use monthly regional irradiance data from the European Commission's Photovoltaic Geographical Information System database (36), and use the actual daily running time of the pumps as reported by local support staff.

However if you wish to make some such point, then better define what you are doing, get the Australian electricity production data from AEMO (half hourly data for all power stations is available), get solar irradiance data from the BOM and go for it.

When the Active Cavity Radiometer Irradiance Monitor (ACRIM I) satellite ended its mission, there was a delay in launching ACRIM II, which meant that data from the Earth Radiation Budget Satellite (ERBS) satellite data had to be used during the intervening period.

Despite apparent artificial issues in long - term measurements of cloud from ISCCP, and the lack of reliability in low - cloud data from irradiance - based satellite cloud estimates, we find the ISCCP and MODIS datasets to be in close agreement over the past decade globally.

The data show a wellestablished 11 - year cycle in irradiance that varies by 0.08 % from solar cycle minima to maxima, with no signifi cant long - term trend.

3, Eric, in line: From examining the data records I conclude: Changes in solar irradiance explain perhaps one - quarter of the increase in temperature during the last century.

Global compilations from ground - based radiometer data (Liepert, 2002), covering the period 1960 - 1990, suggest a substantial decrease in solar irradiance reaching the ground.»

Given that the blackbody equilibrium temperature of earth as seen from space is a function of solar irradiance arriving and earth albedo and not much of anything else apart from factors that change those two, anyone claiming earth's temperature isn't affected by solar output better have a pretty good theory and data to support that.

Estimation of the downward longwave irradiance reaching the Earth surface derived from SEVIRI data on board the geostationary satellite Meteosat.

Total solar irradiance is reconstructed using data from the spectromagnetograph on Kitt Peak for 1992 — 2003 (covering parts of cycles 22 and 23) and compared with observational data.

Downwelling irradiance measurements, data from AERONET and EARLINET (Europe), or satellite imagery are operationally available.

Atmospheric gases and solar irradiance values from 1861 to 2000 helped produce a suite of atmospheric, ocean, land, and sea ice gridded data.

There is a further and more fundamental issue with the satellite cloud data that makes any claim of a connection between low - cloud properties and solar activity highly suspect: we argue that it is not possible to accurately determine low cloud variations from satellite - based irradiance techniques.

Foster and Rahmstorf characterize ENSO by using the Multivariate ENSO Index (MEI), aerosol optical thickness data (AOD) for volcanic activity, and solar irradiance data (from PMOD) to characterize solar activity.

It was in fact 2 things an energy decrease from solar irradiance in the 11 year cycle and a change in cloud cover that is associated with ENSO resulting in less reflected SW — seen in the CERES data.
