About Ice Cores | NSF Ice Core Facility

The National Science Foundation Ice Core Facility (NSF-ICF) — formerly the U.S. National Ice Core Laboratory (NICL) — is a facility for storing, curating, and studying meteoric ice cores recovered from the glaciated regions of the world.

Earth Observing System (EOS)
SeaWiFS, TRMM, Landsat 7, QuikSCAT, Terra, Aqua, Aura, CloudSat, CALIPSO, SMAP

A-train is a satellite constellation of 7 EOS satellites. They are spaced a few minutes apart from each other, so they can be used together to build 3D images of the Earth’s atmosphere and surface.

A snapshot of the simulated time evolution of the component of atmospheric carbon dioxide (CO2) concentration originating from the land surface for February 1900. CO2 is transferred as NEE from the Community Land Model Version 3 (CLM3)—coupled with the CASA′ terrestrial biogeochemistry model—to the Community Atmosphere Model (CAM3)

Navier-Stokes Equation of Mean Motion:The balance of all the forces in the eath’s atmosphere w/o centrifugal force

 

In a turbulent atmosphere, a turbulent stress term, the Reynolds stress, must be applied.

* Terms can be neglible in some cases:

    1. For steady-state flow, the tendency --> 0.

    2. Above horizontaly homogeneous sfc, the adv. --> 0.

    3. In the center of high/low pressure areas or for small scale processes,
            the PGF  --> 0.

    4. At the equator, Coriolis term --> 0.
