NOTICE TO USERS
Commander, Naval Meteorology and Oceanography Command is consolidating the command's web presence in accordance with Department of Defense (DoD) and Navy guidance. The U.S. Naval Oceanography portal will be the single access point for all public facing Meteorology and Oceanography products and services. This publicly-accessible portal is currently online at http://www.usno.navy.mil and is being populated. In the near future, non-DoD users will be redirected to this portal.
DoD customers can access all operational data, products and services via the NIPRnet Naval Oceanography Portal site at https://oceanography.navy.mil (CAC required).
The Web version of MICA has been discontinued and ceased to function on 31 December 2005. This has become necessary because the data provided by this service utilized the MICA 1.0 software, which is now obsolete. A selection of the most popular Web MICA calculations are available in other data services on our Web site. However, the less-popular Web MICA calculations are no longer be supported. Please refer to the table below which summarizes alternative sources of the data formerly provided by Web MICA.
For those MICA calculations that will no longer be available on the web, consider obtaining the MICA 2.0 application, available for both Windows and Mac OS-based computers. All of the calculations that could formerly be performed through the MICA web page can be done with MICA 2.0. In addition, the MICA 2.0 application has many new features, including: an expanded date range (1800-2050); a phenomena calculator; ephemerides of Jupiter's Galilean satellites and selected asteroids; the JPL DE405 lunar and planetary ephemerides; and updated astrometric catalogs.
