  13. Summary. Access of low energy cosmic rays to any position on the Earth depends on the state of the magnetosphere. Anisotropy of cosmic rays, deduced from the neutron monitor network, must assume the variable transmissivity of the magnetosphere especially during the geomagnetic disturbances. We illustrate that computations based on different available models of geomagnetic field during selected strong geomagnetic disturbances in 2003 and 2004 imply different profiles of cut-off rigidities in time, different transmissivity functions and different asymptotic directions. Using of cosmic ray records by neutron monitors at middle and low latitudes during geomagnetically active periods, in addition to cosmic ray anisotropy in interplanetary space deduced from high and low energy cosmic ray ground based measurements, may be used for checking validity of geomagnetic field models. By K. Kudela, R. Bučík and P. Bobík Checked 3 types of differencies:

  14. Differences of Ts89, Ts89+Dst, Ts04: 1. Transmissivity function: Ts89 Ts89+Dst Ts04 TF (for vertical direction) for Lomnický Štít before the onset of the storm (Nov. 20, 2003, 02 UT, black) and during the Dst minimum (19 UT, red) for three models.

  15. 2. Asymptotics. Asymptotic directions for Lomnický Štít before the disturbance (upper panels, Nov. 20, 2003, 02 UT) and at minimum Dst (lower panels, 19 UT) for Ts89+Dst (left) and Ts04 (right).

  16. 3. Timing of minimum cut-off rigidity. Rome neutron monitor. Increase in CR is matching better the cut-off decrease for Ts04 model than that for Ts89 + Dst.

  17. Different models of magnetic field (external sources) during strong geomagnetic disturbances give different estimates of (a) Time profile of cut-off rigidities at a particular ground station (b) Transmissivity function for particles coming from outside magnetosphere (c) Asymptotic directions CR increases at middle and high nominal cut-off NMs are observed superposed on FD (earlier papers in appendix). Model with prehistory (Ts04) and model with Dst give different results for two storms (comparison of CR peak time vs time of maximum cut-off depression). No general conclusion about validity of models from this limited study.

  18. How to check validity of geomagnetic field models by CR during geomagnetic storms? Timing of maximum CR increase vs minimum predicted cut-off at many stations (?) Very simplified: simultaneous change of CR anisotropy in interplanetary space (CME passing Earth’s orbit) Spaceship Earth (Bieber J.W., P. Evenson, ICRC, 1995), ring of NM at high latitudes – anisotropy at low energies (not strongly affected by magnetospheric disturbance – asymptotic directions in narrow interval of longitudes, close to ecliptic, changes below atmospheric cutoff) – reference for IP anisotropy at LE ? Network of muon directional telescopes (Munakata K. et al., Adv. Space Res., 2005) studiesanisotropy at energies above NM (~50 GeV), not strongly affected by changes in magnetosphere – reference for IP anisotropy at HE ?

  19. Using predictions of different models (disturbed field) for (a) time profile of vertical cut-offs, (b) asymptotic directions and (c) transmissivity function for low and middle latitude NMs plus coupling functions and Anisotropy estimate at “middle energies” from interpolation between anisotropy in IP space by Spaceship Earth (LE) and by Muon Telescope Network (HE) To estimate CR time profiles at various NMs (middle, low latitudes), to compare with measurements by NM network ? Problems, simplifications: energy spectra of primary particles, only vertical direction assumed. In addition: proton detector(s) with high geometric factor at low orbits can check the consistency of transmissivity functions at two altitudes (model dependent). More systematic studies needed: different storms, network of NMs, better temporal resolution of NMs.

  20. Concluding remarks CR measured by NM at middle and low latitudes can probably help in testing validity of geomagnetic field models during strong disturbances. IP anisotropy deduced from lower energies (Spaceship Earth) and high energies (muon telescopes) as well as low altitude polar orbiting satellite(s) with large geometrical factor for energetic particles are useful for that.
