Hi Michael, Joei, Henry and Ben For the year 2002 designated "y" that includes everything, NCEP, Solar F10.7, Kp I propose the following quantities for the 2 regions: E-region densities are assumed to be in photochemical equilibrium so there is no dynamic wind or ExB drift influence - only changes in temperature, and composition influence the electron density. E-REGION QUANTITIES at 110 km _______________________________ Neutral Temperature Atomic Oxygen Molecular Oxygen Molecular Nitrogen Nitric Oxide Electron density F-region densities are influenced by dynamics, both neutral wind and ExB and composition and temperature so you probably want the quantities indicated below. F-REGION QUANTITIES ar HMF2 _______________________________ Neutral Temp Neutral Zonal Wind Neutral Meridional Wind Vertical Wind Molecular Oxygen Atomic Oxygen Molecular Nitrogen Zonal ExB Drift Meridional ExB Drift Vertical ExB Drift Electron Density HMF2 FOF2 Geopotential Height I propose two processor runs 1. For the E-region with quantities indicated and 2. For the F-region with quantities indicated for the following stations: Chilton Port Stanley Moscow Wakkanai Wallops Eglin Hobart Please look these over and if I get the OK from Michael Ben and I can start the processor runs. Thanks, --Ray *************************************** From mendillo@bu.edu Tue Feb 14 07:40:35 2006 Date: Tue, 14 Feb 2006 09:40:32 -0500 (EST) Subject: Specification of Model Output Parameters for Studies From: mendillo@bu.edu To: roble@hao.ucar.edu Cc: jwroten@bu.edu, hr@phys.soton.ac.uk Hello Ray, I agree with the agenda proposed by Henry, and so let me answer your question about what parameters we should have for analysis. Recall that we are interested in parameters for the F2-layer (meaning parameters at the Nmax height=hmF2) AND for the E-layer (taken as 110 km all the time). In the recent set of output for the first 60 days of 2002 you sent to Joei, the parameters (fields) were: -----Let me call this Set A -------- Neutral Temperature Electron Density foF2 hmF2 Atomic Oxygen Nitric Oxide Ratio O/(N2+O2) Electric Potential Obviously, in Set A the Nitric Oxide density is not needed at hmF2, and the foF2 and hmF2 are not needed at 110 km. In our previous studies for the F2-layer only, we had the following parameters (though we did not use them all in publications): ----Set B ---------- Neutral Temp Neutral Zonal Wind Neutral Meridional Wind Vertical Wind Molecular Oxygen Atomic Oxygen Molecular Nitrogen Zonal ExB Drift Vertical ExB Drift Electron Density HMF2 FOF2 Geopotential Height This is a more comprehensive set that exploits full GCM capabilities, but I do not know how difficult it is to get all of them with your new runs. So, I would suggest two options: (1) Add meridional winds to Set A. (2) Use Set B "as is" for F2-layer (could delete foF2 as redundant to electron density at hmF2). Add the same set for the E-layer (at 110 km in place of hmF2), PLUS the Nitric Oxide value at 110 km. These would all be at your grid points closest to the "usual ionosonde stations" at: Chilton Port Stanley Moscow Wakkanai Wallops Eglin Hobart Please let me know what you think about this. Good to be starting on this project again!
