Comprehensive Model (CM4) Interface (single point evaluation)

Click here to evaluate on a grid and/or produce maps
Compute J along with B: yes: no:
Get DST from file:
If not, provide DST value (nT):
yes: no:
Get F10.7 from file:
If not, provide F10.7 value (10-22W/m2/Hz):
yes: no:
Compute MUT from UT:
If not, enter MUT value (hours)
yes: no:
Geocentric or Geodetic:
Use core/lithospheric sources: yes: no:
If using core/lithospheric sources,
enter Min-Max spherical harmonic degree for first evaluation (1 to 65):
and Min-Max spherical harmonic degree for second evaluation (1 to 65):
If max is less than min, then c/l will be disabled for that evaluation.
Use magnetospheric sources: yes: no:
Use ionospheric sources: yes: no:
Use insitu (coupling) current sources:
If insitu current sources, from Magsat instead of Oersted:
If from Magsat, from dawn LT instead of dusk LT:
yes: no:
yes: no:
yes: no:
The Comprehensive model is not a predictive model and should not be relied upon to give accurate results outside of the envelope of data used in the model. The current envelope of data extends from 1960 to February, 2011 (except for core sources, which extend only to July 2002). If you do not specify DST and F10.7 values, the latest date that you may specify is approximately 2011.1.
Universal time (1960 to 2011.1 years):
