Hi.Thanks. How do you obtain the diffuse and direct irradiance data after correction? I don´t have the atcor tool, i made the correction with the model maker
Dear Sanjoy Roy, Thank you for this video . I asked you a little offline : you 've never run with SPOT 5 satellite image data yet? Thanks in advance! Best regards Pham ngoc Quang
+Sanjoy Roy thank you for your reply.I need tutorial/direction on MODTRAN. Actually I want to use MODTRAN5 to measure atmospheric transmittance from RTE for land surface temperature retrieval. Could you please help me on this particular topic.
sir i am trying haze correction for landsat 8 before atmospheric correction, but its showing "strange hot Histogram" or "no clear pixel" found something like that,, PLease guide How can i get rid of this problem..Thank you..
+Suman Chatterjee Yes, I think you are working in ERDAS Imagine environment (Atcor module) , right? You do one thing- Subset your image first up to your area of interest. After that, you try to operate Atcor on this subset image. I hope this will rescue you from that problem.
Sanjoy Roy Thank you sujoy.. yes i am using in erdas imagine environment,,,,and I am doing the process after subseting but still same result is coming...
I am Using Landsat 8 OLI Sensor image...And Yes I have prepared .cal file with the template comes with atcor. i am running atmospheric correction and it is working well but whenever i am trying for Haze correction its showing the above mentioned problem...
Respected sir, I abhishek kumar ojha thanking you for making this video but request for favor if you are using erdas crack version of 2014 then please send me the ATCOR 2014 crack file. For which i will be really grateful because i had been unable to process because i dont have licence product. so if you can please help me.

Thank you fr the tutorial but how do you make sub_stack.img?by using the same software?

Can you send atcor for erdas 2015
could you explain how you calculated the solar zenith from the sun elevation?
90 degress minus solar elevation angle
How do you create the calibration file?
@Sanjay Roy
sir, How can i prepare the cal file in excel? i am having trouble to prepare. can't understand
Great work. Thanks so much, it has help me.
+Aniekan Eyoh Keep Update with my channel and learn a lot !!
Thank you very much for your video, just a quick question how can i obtain excel file to calculating Solar Zenith pls. Thank you
90°- sun elevation.
hy,I found this helpful.Do you have any video tutorial or materials on MODTRAN software?
+Tany Karen No, not yes,,,But you can follow my tutorial "Atmospheric correction FLAASH". FLAASH uses Modtran to correct image atmospherically.

I will try

Sanjoy Roy Thank you sujoy.. yes i am using in erdas imagine environment,,,,and I am doing the process after subseting but still same result is coming...
+Sanjoy Roy the actual message showing is "No clear land pixels found: haze correction not possible."
+Suman Chatterjee which sensor( satellite image) you are using? Have you prepared the .cal file from image metadata?
I am Using Landsat 8 OLI Sensor image...And Yes I have prepared .cal file with the template comes with atcor. i am running atmospheric correction and it is working well but whenever i am trying for Haze correction its showing the above mentioned problem...
