IPS Solar Wind Speed Database
1. Name of Database: IPS Solar Wind Speed Database
2. Institution: Solar-Terrestrial Environment Laboratory, Nagoya University
3. Contents of Database:
This database includes solar wind speed data obtained from interplanetary scintillation (IPS)
measurements with the multi-station system of the Solar-Terrestrial Environment Laboratory,
Nagoya University. IPS measurements allow us to probe the solar winds near the sun or at high
latitudes, which are inaccessible to in situ measurements, in a relatively short time. This
database covers the period from 1973 to 2002 (at the present). Users can make various kinds
of graphic plot on a WWW browser using the IPS solar wind speed database system.
4. Examples of Database:
IPS solar wind speed data taken in 1999 (in text format)
---------------------------------------------------------------------
HLA, HLO: Heliocentric latitude and longitude
GLA, GLO: Heliographic latitude and longitude
Longitude and Carrington rotation number are not
on the source surface but at the P-point
An error of -999 means
only two stations could be used to calculate the speed
