Magnetospheric State Query System (MSQS)
Goddard Space Flight Center, NASA
This Magnetospheric State Query System (MSQS) is developed as a part of our effort to construct a set of new-generation radiation belt models. As a stand-alone system, the MSQS returns the time intervals when a set of user-specified geophysical conditions occurred. Time intervals from MSQS can be used directly to select, retrieve, and analyze the observations associated with a given magnetospheric state [Fung, 1996; Fung et al., 2005; Fung and Shao, 2008]. Definitions and explanations of MSQS quantities can be found here .

Please acknowledge/cite the use of the Magnetospheric State Query System (MSQS) in your publications or presentations by the following phrase:

"For this research, I/We have made use of the Magnetospheric State Query System (MSQS) developed and operated by the Space Physics Data Facility of NASA's Goddard Space Flight Center."

F10.7 is Solar flux density at 2800 megaHertz with unit = 10^-22 Joul/sec/m^2/Hz.
Solar wind Bx, By, Bz are in GSM coordinate.

User can specify the magnetosphere state (PSI) parameter range (minimum to maximum) and retrieve multi time intervals satisfying the query conditions.
Delay factor must be non-positive integer.
Ave. over (ave_len) stands for the time duration for "Averaging over" and must be positive integer.
By checking the box in front of the parameter f and specifying the Min, Max, Delay and Ave. over values, the time intervals t retrived will satify
