That turns out to be a generally useful capability, and a different part of the Map team is able to reuse that for a satellite - imagery analysis task where they wanted to find roof tops in the U.S. or around the world to estimate the location of solar panel installations on rooftops.

«Software can come in many different forms; it can simulate data, it can incorporate your algorithms, or it can be used for statistical analysis of your results — it's really a geomatics tool that can be used from end to end,» says Cannon, a professor of geomatics engineering at Calgary and an expert in the research and development of satellite navigation tools used by land, marine, and airborne vehicles.

Using many different types of analysis, they found that their model closely matched the satellite observations.

Despite several new analyses with improved cross-calibration of the 13 instruments on different satellites used since 1979 and compensation for changes in observing time and satellite altitude, some uncertainties remain in trends.

The mean insolation at Earth orbit is about 1366 W / m ^ 2; the peak - to - peak variation over the 11 year solar cycle is about 3 W / m ^ 2; the authors discuss two running averages derived from different satellite data sets and analysis derived by Willson and Mordvinov (2003) and Frohlich and Lean (1998) respectively.

Looking above Earth's surface at certain layers of the atmosphere, several different analyses examined NOAA satellite - based data records for the lower and middle troposphere and the lower stratosphere.

There has been a debate on the trend estimates from a number of different studies based on the Microwave Sounding Unit (MSU) instrument carried by a number of satellites, and different researchers have come up with different trend estimates depending on how they have carried out the analysis.

The mean insolation at Earth orbit is about 1366 W / m ^ 2; the peak - to - peak variation over the 11 year solar cycle is about 3 W / m ^ 2; the authors discuss two running averages derived from different satellite data sets and analysis derived by Willson and Mordvinov (2003) and Frohlich and Lean (1998) respectively.

Much of the team's analysis was conducted using data from two different satellites - ICEStat, and GRACE which measure changes in ice mass using lasers and change in the earth's gravimetric field respectively.

The monthly mean averages and trend analysis input files necessary for the purposes of this study were then created using the daily comparison measurements with two different sets of only coincident datasets being considered: the monthly mean and associated standard deviation of the ground - based measurements and the equivalent one for the satellite measurements.

Such an assessment should involve a detailed analysis of the sensitivity of global - mean temperatures derived from these three different measurement systems to the various choices made in the processing of the raw data — e.g., corrections for instrument changes, adjustments for orbital decay effects in the satellite measurements, and procedures for interpolating station data onto grids.

I agree with you that the last decade really doesn't tell you that much about the long term trends, given the size of the error bars, but it does allow for some interesting analysis of the difference between individual temperature records during that period (e.g. ENSO responses of satellites vs. surface measurements, effects of different ways of treating arctic temperatures, etc.).

There are other satellite analyses that have found different numbers but I've not had a chance to look into that recently at all...

We repeat the analysis for the NCEP and satellite epochs to establish that the approach is robust for datasets of different lengths, and we examine the evolution of decadal power in the natural influences to assess their projections onto each other as sources of error in prior results.

Although several different algorithms have been used to derive sea ice concentrations from the satellite measurements, our analyses based on the Hurrell et al. (2008) data are consistent with previous studies.

A comparison of Australian mean temperature from a range of different datasets — including local and international datasets (which use different methods of data selection, preparation and analysis) and both station - based and satellite data — is provided below (Figure 12).

The satellite temperature record comes from a succession of different satellites and problems with inter-calibration between the satellites are important, especially NOAA - 9, which accounts for most of the difference between various analyses.

Uncertainties should decrease closer to near - current dates (e.g. from denser and more accurate sampling)-- but note that these products also employ different QC and analysis methods, rely to varying degrees on satellite data, on sea - ice data to constrain polar SST, and on bias adjustments for historical changes in measurement methods.
