ArrayList not displaying when first referenced in function

Asked 2022-Mar-31 at 19:25

Facing a couple logistical issues in PowerShell - clearly I'm missing a basic concept:

Setup: Create the menu.ps1 file (shown below), launch PowerShell 7.2.2 and call the file locally.

Issues:

The first time you choose option 1 for the ArrayList ($psArrayList), it does not display (although we see from the initial screen load that the items are populated). If you return to the menu and choose option 1 again, it will display on the second pass. ($psArray does load fine on first try, so is this is a type issue.?)
When the script ends, $psArrayList and $psArray are still in the current session variables, as indicated by: Get-Variable psArray*. Even if I instantiate them with $script:psArrayList = [System.Collections.ArrayList]@() and $script:psArray = @() they seem to stay within the session scope. Is there a "right" way to clear them when the ps1 ends?

Regarding the first issue, you would need to use Out-Host or Out-Default so that both outputs (Write-Host together with the arrays) are correctly displayed to the console. See these helpful answers for in depth details on this:

Regarding the second issue, your End-Script function would have a scope issue, Remove-Variable is trying to remove variables defined inside the function's scope (Local), if you want to target the variables defined outside it (Script), you would need to use the -Scope parameter, for example:

I really wouldn't recommend shelling out subprocesses from Python to call ImageMagick thousands of times. You'll just end up including too much process creation overhead per image, which is pointless if you are already running Python which can do the image processing "in house".

I would suggest you use PIL, or OpenCV directly from Python, and as your Mac is certainly multi-core, I would suggest you use multi-processing too since the task of doing thousands of images is trivially parallelisable.

As you haven't really given any indication of what your tuples actually look like, nor how to determine the output filename, I can only point you to methods 7 & 8 in this answer.

Your processing function for each image will want to create a new transparent image then open and paste other images with:

QUESTION

MetPy interpolate_to_grid function returning unexpected nan based on data domain

Asked 2021-Nov-02 at 22:53

I have been using the "Gridding METAR Observations" example code from MetPy Mondays #154 for some time without any issues. Up until recently, I passed the entire data set without restrictions (except to exclude stations near the South Pole, which were blowing up the Lambert Conformal transformation.)

Recently, I tried to restrict the domain of the METAR data I process to North America. At this point, MetPy's interpolate_to_grid function seems to be returning nan when it did not previously. Since my region of interest is far removed from the boundaries of the data set, I expected no effect on contours derived from the interpolated data; instead there is a profound effect (please see the example below.) I tried to interpolate over regions of missing data (nan) using SciPy's interp2d function, but there are too many nan to overcome with that "bandaid step".

Question: Is this expected behavior with interpolate_to_grid, or am I using it incorrectly? I can alway continue to use the entire data set, but that does slow things down a bit. Thanks for any help understanding this.

In the following example, I am using the 00Z.TXT file from https://tgftp.nws.noaa.gov/data/observations/metar/cycles/, but I am seeing this with METAR data from other sources.

ANSWER

Answered 2021-Nov-02 at 21:58

This was a tricky one to figure out. What's going on is that MetPy's implementation for Cressman (and Barnes) interpolation uses a maximum search radius for points included in the distance-weighted average. If you don't specify this maximum search radius, it uses 5 times the average minimum spacing between stations.

By subsetting your data to approximately North America, you have constructed subset of the data where the stations are closer together; this results in a smaller search radius (it is decreasing from ~150km to ~66km). This is obviously producing suboptimal results for your dataset, I think in part because there are limited stations. I plotted the station locations on top of the results using a 66km search radius here:

You can see the dropouts are where there are sizable gaps between stations. The best solution here is to manually specify the search_radius argument to something like 120km, which seems to give reasonable results:
