NASA will be performing network maintenance on Wednesday, November 20, 2024, between 11:00 AM EST and 1:00 PM EST (16:00 to 18:00 UTC). There will be two periods of about five minutes of disruption. During these peroids, the ILRS website will be unavailable during the outages. If you experience problems outside this window, contact support-cddis@nasa.gov.

Summary


  • Ciddor-Mendes refraction formula: Awaiting reviewed publication
  • Assessment of group velocity concept (P.Ciddor)
    • first order approximation in absorption, second order in dispersion
    • worst case assupmtions for laser spectral width, slope of absorption
    • currently under revision by Y.Galkin
    • Preliminary result for wavelengths far from absorption lines:
      • Group velocity concept is applicable for fourier limited pulsewidths >10ps and propagation distances <40km
  • Crosscheck of Ciddor-Mendes refraction formula with distinct approaches
  • Assessment of horizontal refractivity gradient effects(R.Haas)
  • Improved modeling capabilities at low elevation angles require assessment of laser wavelength parameter accuracy.
