Well I am still getting familiar with GeoNet too, but this is what I just tried (and it worked for me):
1) Click on the attachment
2) A pop up is displayed and one of the options is to save.
3) You should see a little blue down arrow when you say okay. If you click on it, you can get the zip file.
If that doesn't work for you I will find someone who can tell us a better solution.
Here is some more information about the Emerging Hot Spot Analysis categories:
*************** Category Definitions ********************
Hot spots that are statistically significant for the last time step interval:
New: only the most recent time step interval is hot
Persistent: at least 90% of the time step intervals are hot, with no trend up or down
Intensifying: at least 90% of the time step intervals are hot, and becoming hotter over time
Diminishing: at least 90% of the time step intervals are hot, and becoming less hot over time
Consecutive: an uninterrupted run of hot time step intervals, comprised of less than 90% of all intervals
Sporadic: some of the time step intervals are hot
Oscillating: some of the time step intervals are hot, some are cold
Hot spots that are not statistically significant for the
last time step interval:
Historic: at least 90% of the time step intervals are hot, but the most recent time step interval is not
Cold spots that are statistically significant for the last time step interval:
New: only the most recent time step interval is cold
Persistent: at least 90% of the time step intervals are cold, with no trend up or down
Intensifying: at least 90% of the time step intervals are cold, and becoming colder over time
Diminishing: at least 90% of the time step intervals are cold, and becoming less cold over time
Consecutive: an uninterrupted run of cold time step intervals, comprised of less than 90% of all intervals
Sporadic: some of the time step intervals are cold
Oscillating: some of the time step intervals are cold, some are hot
Cold spots that are not statistically significant for the last time step interval:
Historic:at least 90% of the time step intervals are cold, but the most recent time step interval is not
We won't be able to get it done for the first release, unfortunately, but in a future release you will be able to select the categories you are interested in and also modify how each category is defined (i.e., right now a persistent hot spot is one where 90% of the time step intervals are statistically significant hot spots and there are no statistically significant cold spots... you might want to change it to 80%, for example).
Beta 5 will have better cell size and time interval defaults when you don't provide anything for those parameters, and messages defining categories.
I hope this helps.
Best wishes,
