NRLMSISE-00 Atmosphere Model

This page enables the computation and plotting of any subset of MSIS parameters: neutral temperature, exospheric temperature, densities of He, O, N2, O2, Ar, H, N, and total mass density.

* Select Date: (1960/02/14 - 2021/05/27 New: End date updating monthly) and Time
Year Month: Day(1-31):
Time Hour of day (e.g. 1.5):
* Select Coordinates
Coordinates Type
Latitude(deg.,from -90. to 90.): Longitude(deg.,from 0. to 360.):
Height (km, from 0. to 1000.):
* Select a Profile type and its parameters:
Start Stop Stepsize

Optional Input parameters:
Note :If user does not specify these parameters,they will be taken from real data base
F10.7(daily)   F10.7(3-month avg)   ap(daily)

*Select output form:
List model data
Create model data file in ASCII format  for downloading

Plot model data 
      Note 1: The first selected parameter below always will be along the X-axis, the other selections will be along Y-axis.
              (e.g. if you want a Height profile, you may specify Height as the first parameter in the listing below.)     
      Note 2: User may get scatter plot if he specifies any two parameters below and changes the "connect type"  
              in the "Advanced plot selections" to "show points only"
