![]() Plot it and fill in the blanks on the answer sheet for Tropical model. Select Model Atmosphere-> Tropical Model.Which brings up the dialog box Model Atmosphere(1).Then go to the next page to do the tropical model, and answer those questions. There are also ways to plot one data set over another, and various other things that you should mess around with, but first answer the first question in the lab.For example:Autoscale: OFFMin X=0.938, Max X=0.946X Decimal = 5 will yield the plot on the next page.So that you can get ridiculously exact about answering the questions in the lab.For example:Autoscale: OFFMin X=1, Max X=1.1X Decimal = 2 (you might have to fiddle with X Divisions too) will yield.If you’re one of those types who has to have the exact answer, you can adjust the plotting parameters as you like.This is probably all you need to answer the first question. Clicking on the plot will show the X and Y location you’ve clicked on the upper left corner. Oh wait, perhaps a little more direction would be helpful. Now we have a plot of transmissivity in the VNIR, and you can answer the questions in lab.The model parameters are reproduced here to make sure that the program is configured correctly.Geometry and Spectral Band (3) lots to do here Aerosols (note that we’re using Rural, with 23 km visibility) – Hit Next.DISORT is used in many atmospheric radiative transfer codes including Streamer, MODTRAN, RRTM and SBDART. Atmospheric Column parameters – hit Next! DISORT (Discrete Ordinates Radiative Transfer Program for a Multi-Layered Plane-Parallel Medium) - general and versatile plane-parallel radiative transfer program applicable to problems from the ultraviolet to the radar regions of the electromagnetic spectrum.Select Mode of Execution -> Transmittance.Select Type of Atmospheric Path -> Slant Path.Select Modtran Input-> Model Atmosphere (1).The PcModwin 4.0 icon should be on the desktop, and you double click on it to get.PC MODTRAN Tutorial How to make an atmospheric model in 47 easy steps. ![]()
