Network Earth Rotation Service
The Network Earth Rotation Service is an on-line tool for dissemination
of the Earth's orientation parameter that describe irregularity in
the Earth's rotation that are determined from observations and partly
from numerical weather models. The service provides an automatic access
to the parameter that describes the Earth's rotation from 1976.01.01
through 48 hours in the future.
- The atmospheric
angular momentum on-line service. The exchange angular momentum
between the lithosphere, atmosphere, and the ocean is one of the
factors that cause irregularities in the Earth's rotation.
- Web interface
to the Network Earth Rotation Service. It displays
selected parameters of the Earth's rotation at the specified epoch.
- Real time Earth
rotation service. Shows the Earth orientation now based
on the forecast. The forecast rms errors of the Earth orientation
parameters at the current moment:
1.1 nrad for components 1,2 (polar motion) and
2.5 nrad for component 3 (axial component, or UT1),
which corresponds to 7 and 16 mm at the Earth's surface
- Generate Earth orientation parameter
series with a specified time range and specified time step.
- Current latency of the NERS.
- Client software for automatic
computation of the Earth orientation parameters.
- How to use the Network
Earth Rotation Service.

Earth Surface & Interior program, grant NNX15AC10G.
