Google Earth Engine中数据的scale问题 近期发现许多同学没有意识到GEE中的scale问题,将从GEE中下载的数据直接拿来用,而且也没发现问题。 GEE中landsat 9数据介绍 如图中bands中,标出的Scale与Offset,在下载数据时需要乘以这个scale并加上offset。 在早期的GEE示例代码中,只有去云的cloudMask代码,但并没有该操作,需要...

Large-scale mantle heterogeneity as a legacy of plate tectonic supercycles Samples from both the shallow and deeper mantle suggest a consistent geochemical dichotomy between the African and Pacific mantle domains that is developed through tectonic supercycles, according to a supervised machine learning ...
In turn, the development of radiometric dating methods has permitted numerical estimates of age to be incorporated in the scale of geologic time. The development of the mass spectrometer has provided researchers with a means of calculating quantitative ages for rocks throughout the whole of the ...
This knowledge also helps identify the risks associated with altering the Earth system with greenhouse gas emissions and regional to global-scale changes in land cover. Stephen T.

Natural Earth solves a problem: finding suitable data for making small-scale maps. In a time when the web is awash in geospatial data, cartographers are forced to waste time sifting through confusing tangles of poorly attributed data to make clean, legible maps. Because your time is valuable,...

This is one of the most interesting finds in Google Earth in quite some time. A few weeks ago a first time poster, called KenGrok, at the Google Earth Community (GEC)discovereda very exact scale model of some mountainous region located in the middle of a desolate area in north central ...
Changes in the seasonal cycle amplitude of atmospheric CO2(SCA) reflect large-scale changes in the global carbon cycle. This Review summarizes the positive SCA trend in the northern high latitudes, where the signal is strongest, and explores the underlying mechanisms driving the trend and their rel...
