AI Thread Summary
To view a .he5 file, which is a format used by NASA for storing large datasets, users can utilize HDFView, a program specifically designed for reading Hierarchical Data Format files. The .he5 format is employed for efficient data management, particularly for extensive datasets like ozone data from NASA's NOAA website. Users can download the required data files directly from the NASA data pool and then open them using HDFView to extract and analyze the information. While the NASA data access page provides instructions for downloading files via FTP, it may not offer clear guidance on viewing .he5 files, necessitating the use of specialized software like HDFView for effective data visualization.

How to view .he5 file??

Not sure if this is the right place in the forum to ask this question. If it isn't, feel free to move it to the appropriate section.

I am trying to obtain some data from the NASA NOAA website for a project I am working on, namely some ozone data from this page:

http://daac.gsfc.nasa.gov/daac-bin/whom/mk_page_cgi.pl?PATH=datapool/MLS_DP/Level2.002/ML2O3/2008/06/06

I checked where it said 'select' in the data file box, then narrrowed down my spatial setting to the region where I needed the data. After clicking the 'submit subset request' I reach a page that has this:

Subsetted Data Download Instructions:

Single file download: click on the file: MLS-Aura_L2GP-O3_v02-23-c01_2008d158.SUB.he5

Multiple file download:
Download the FTP_script: order_21205.txt
On SGI or Linux machine, run: ftp -p -n acdisc.gsfc.nasa.gov < order_21205.txt
On DOS, SunOS or Windows/Mac platforms, run: ftp -n acdisc.gsfc.nasa.gov < order_21205.txt


My question is, how does one view a .he5 file?? I have never seen this before. Additionally, this page attempts to offer assitance but I have no idea what it is telling me to do:

http://daac.gsfc.nasa.gov/data/datapool/HELP/DATAPOOL/A_access_data.shtml


Can anyone offer any help as to how to extract and view this data?? Or if possible, can someone just extract it and paste it here? Thanks for any help you can give me, this is sort of important.

The page just describes how to downloadthe files from ftp - useful advice for 1990 but less so now.

googling ".he5 file" the first two hits gives papers describing the file format, it looks like you will have to write something to extract the data.
Odd that they should use such an opaque binary file format when there are already NASA standards like FITS for this sort of thing.
 


Thanks. Managed to download a program called HDFView that reads those kinds of files directly. I guess the latest creation of the Hierarchical Data Format for Earth Observing System related data, or the so-called "he5" data file, is used by NASA in instances where there is a lot of data that would otherwise create a prohibitively large sized file. Who knows, who really cares. Just glad I found a program to read it.
 


Moved to "computers" since I think it fits best here.
 
In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...
Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
