Hi, I'm a new user, so this suggestion may not be as relevant as I think right now. Anyway, in the Hydrolight/Ecolight GUI, if you want to click rapidly...
Last week I installed Norton 2010 anti-virus anti-everything software on my home computer. When I did a Hydrolight run tonight that required recompilation,...
Greetings, There have been some recent questions about running HE5 under the Lahey Fortran 95 Express version 7 compiler on computers with 64 bit Vista. LF95...
Greetings HE5 users, I have just posted a file, Updates.zip, to the files section of the Users' Group website. This file contains various "revison 1" updates...
Has anyone parallelized Hydrolight and/or Ecolight to run on either multicore processors on a single machine (requiring rework of code to be reentrant) or on...
Hello All! I am newbie to HE5. I have hyperspectral radiometer data with chl profiles and CDOM concentration profiles in ppb/l. Now how can I specify CDOM's...
Finally, at long last, HydroLight-EcoLight version 5.0 (HE5) is now shipping! All licensed version 4 users will receive HE5 as a free upgrade. To receive your...
Hello HydroLight users, Marcos Montes and Joe Rhea of the U.S. Naval Research Lab recently noted that the solar azimuthal angle computed by HydroLight when you...
I have just posted HydroLight Technical Note #6 (file HTN6_infdeep_sources.pdf). This note discusses the sometimes puzzling behavior of the light field near...
Dr. Minsu Kim has created an Ocean Optics Phytoplankton Simulator (OOPS) that lets you build up IOPs for different types of phytoplankton, including effects 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 ,...
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 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...
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...
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...
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 ...
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...
I have added a HydroLight Technical Note HTN5_Color.pdf discussing the conversion of spectra to CIE (x,y,Y) and RGB values. The current H4.3 version outputs...
Hi everyone, I've submitted a file at that describes a faster version of the selpfbb subroutine. This subroutine is mostly used when there are measured values...
Using the same IOP value as input with homogeneous and infinite deep water body assumption, the maximum output depth is set 1m for one run and 5m for another...
Hi everyone, In the next weeks I am going to (try to) compile the main original Hydrolight fortran code under linux/unix. Among people using the version 4.2 of...
Greetings, Marcos Montes and Joe Rhea at the Naval Research Lab-DC have put together a nice tech note on selection of output depths when fluorescence or Raman...
HydroLighteans, A new H user has just asked me if anyone has developed a frontend (in IDL, for example) that would allow him to run H under UNIX without going...
Hello again, In response to a user's question, I have posted a note about the rho values defined in my 1999 Applied Optics paper on the determination of Rrs...
Hello HydroLight users, I have posted five pdf files on the Yahoo site. These discuss various topics that may be of interest: improvements to the RADTRAN ...
Hello HydroLight users, My apologies for not being more active with this users' group, but I have all of the usual excuses of overwork and laziness. As you may...
