If I use the full radiance output setting, the angle I get is below the water or in the air or depends on the which depth I am gettting from? thanks...
The directions in H are defined by the partitioning of all directions into "quads", as shown in Fig 2 of the Users Guide, and as described in section 2.4 of...
So in the full radiance output file, if the radiance is just below the water surface (like say 0), the angle in that radiance table (theda and phi) should be...
Correct. Thus a direction of theta = 45 deg, phi = 90 deg, is the same direction either above or below the surface. The theta,phi coordinate system does not...
Hi everybody, I would like to use the spectral downwelling irradiance measurements we performed above water surface instead of the Radtran sky model. With the...
Servet (and all), Even though the input file for your two runs look the same, the aren't the same run. The reason is that when you select RADTRAN, it ...
Servet and everyone, In Hydrolight (HL), not everything is controlled by the input file. Some parameters are specified in the input file. Some are specified in...
Folks, Marcos is correct that modifying runs outside of the UI is a task that requires a lot of courage and should not be done cavalierly. I also wanted to add...
I understand it much better now, especially after Marcos' comments. Thanks Marcos, thanks Lydia. One more question: Looking at my newly compiled incfiles.for,...
Servet, Ah, good, you found incfiles.for. When I wrote the email, I had forgotten the incfiles.for is the actual one that gets compiled. There is also a copy...
I understand it much better now, especially after Marcos' comments. Thanks Marcos, thanks Lydia. One more question: Looking at my newly compiled incfiles.for,...
Servet, ... Note that the above steps do not perform a compilation. They merely consist of editing files. Really, I need to add a few steps: First, you should...
Hi Marcos, Thanks a lot for your precious comments. I'll try to write a fortran routine that will read the diffuse spectral irradiance along with Edtot. best ...
It really looks like the most important information is Eddif and eddir if you look at what the skyirrad subroutine returns. Since those are the only things...
Hello everyone, I am a new Hydrolight's user. I would like to know if there is any way to increase the maximum number of bands in the multi-wavelength ...
You can change several limits, including the maximum number of wavebands within the UI. From the RUN ID form at the beginning of the UI, select "change limits"...
Hi all: Can I ask a question about HL? I read a message talking about a Linux version of HL? Has someone suceeded in this effort? If so, how can I get a copy...
Hi Zhiquang You can always compile the source code under Linux. I succeeded under Linux with the (commercial) Intel fortran compiler. But this means that you...
Hello Zhiqiang, Are you sure you don't want to run HL through "wine" in Linux and avoid compiling? It's very easy. First install "wine". Then using the GUI, in...
Hi Zhiqiang, Just in case you might want to run the HL DOS executable in Linux through wine, I figured out that you don't need to create a FAT32 partition. Now...
Hi Zhiqiang and Servet, I have installed HL in a FAT32 partition and used the HL executable and the GUI through Wine. I had to install the MSVBVM60.dll and ...
Hi Elena, As I wrote in my message, I did not pursue the challenge of running the GUI through Wine because I did not really need it. However I am pretty sure...
As I understand the Hydrolight, the GUI creates incfiles.for which contains a number of appropriate subroutine calls. This file is then used in compiling an...
In H4.2, all of the required user input for a run is provided by incfiles.for and iroot.txt. As long as you can provide those two files, and handle compiling,...
hi, everybody I am trying to extend the hydrolight simulation up to 300nm. Here is what I did. I extended gcirrad.txt file to 300 nm as well as input data for...
Jing, H version 5, which is now almost ready for release, runs down to 300 nm. As for help with your specific problem (since I don't know exactly what you've...
Dear HydroLight users, Two sharp-eyed users just found a bug in the subroutine that reads in depth profiles of CDOM absorption at a given wavelength (values of...
Hi everybody, I would like to test a LUT approach but the computer time requirement is huge if I want to cover the full extent of our local IOP, R bottom ,...
