NASA 将这项新的学科命名为“地球系统科学”。NASA地球系统科学委员会成立于1983年[41],旨在支持地球观测系统卫星和相关研究,通过相关观测、建模和过程研究,推动地球系统科学定义的不断发展。NASA领导的研究计划还开发了地球系统的视觉表征,其中最著名的是 NASA 的Bretherton 图(NASA Bretherton Committee diagram,见图4...
2.5Earth Radiation Budget Data CERES (Wielicki et al.1996) currently flies multiple instruments on Terra, Aqua, S-NPP and NOAA20 satellite platforms, collecting and processing broadband shortwave (SW) and longwave (LW) radiances since March 2000. Here, we make use of the CERES Energy Balanced ...
According to the article, authorities in Kiev are expected to attract $37 billion in outside loans in 2024 to cover the budget almost entirely, but in the first half of the year they managed to receive only a quarter of that sum. At the same time, the burden on the Ukrainian budget is...
The great astronomer and thinker Carl Sagan suggested Voyager take the image before NASA shut down the camera to save energy. The vista didn't disappoint. As Sagan wrote: Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone...
Evaluating carbon’s candidacy as a light element in the Earth’s core is critical to constrain the budget and planet-scale distribution of this life-essential element. Here we use first principles molecular dynamics simulations to estimate the density and compressional wave velocity of liquid iron-...

Schematic diagram of upscaling wetland methane emission from site level to global scale. Machine learning methods include decision tree (DT); random forest (RF); extreme gradient boosting (XGB); artificial neural network (ANN); Gated Recurrent Units (GRU); and Long Short-Term Memory (LSTM). PD...
NASA's budget this year and next will be announced in April after the MIRT review is completed, NASA Administrator Bill Nelson told reporters at the time. Join our Space Forums to keep talking space on the latest missions, night sky and more! And if you have a news tip, correction or ...
L.D. would also like to thank NASA JSC and the Lunar and Planetary Institute for the training received at the 4th training in extraterrestrial sample handling course. This work was funded by the UK STFC consortium grant numbers ST/T002328/1 awarded to M.R.L. and L.D. and ST/N000846/...
In these cases, average energy fluxes are used only for comparison with other ones. In addition to the diagram of Figure 6, we construct also the energetic balance related to the cold phase of the glacial circle on the basis of the Antarctica data. Let us assume that the global temperature...
