Observations / Re: What are your end-of-month climate statistics according to WeatherCat?

Dear WeatherCat observers of the changing climate,

Okay, this time I get to start the observations for February.  As usual, I'll give a plug to Grand's WeatherCatRCP:



We expected rain during the night, so I waited to pick up the data until this morning.  All in all, very similar to January.

So who's next?

Dear WeatherCat observers of the seasons turning,

The days are definitely getting longer around here and we are having something of a heat wave for February.  This afternoon we had some pretty clouds that created a different kind of scene than my usual photographic style:



Spring isn't here yet, but winter is definitely starting to wind down.

I don't know the specifics behind the rss format, but that XML's <item> element, hypothetically, could throw things. I don't know how strict the WC's XML reader is. Otherwise the XML looks right.

As for data, I noticed your number localization uses commas instead of decimals. Perhaps WeatherCat isn't understanding the commas? If possible, for the data values it might be worth switching to decimals instead of commas.

The data format is told here: https://wiki.trixology.com/index.php?title=Release_Notes#V2.1.0_-_3rd_April_2015

Added a generic XML based station driver. This connects to your server via HTTP and expects to read the real time weather data as an XML document.
In the I.P. field of the Station Communications window in WeatherCat enter the URL to the document - typically something like myserver.com/my_weather.cgi?action=1
From the XML document received, the following keys will be decoded:
AirTemp_C, IntTemp_C, T1_C, T2_C, T3_C, T4_C - External, internal and 4 additional temperature sensors (°C)
RH, IntRH - External and internal relative humidity (0-100)
Solar - Solar radiation (W/M^2)
UVIndex
Barometer_hPa - barometer in hecto-pascals
WindSpeed_ms - windspeed in m/s
WindDirect_deg - wind direction in degrees
Rain_mm - rain in millimetres - can be accumulating rain or daily rain
The format of a data item in the document should be of the form:
<value>
<name>item name</name>
<data>item value</data>
</value>
for example:
<value>
<name>RH</name>
<data>52</data>
</value>
Notes:
1. The weather server is polled every 3 seconds.

but I really don't understand how this should work. There is reference for .cgi web page, and basic searching from web doesn't make me smarter with this..
I can modify the rss.xml file output and will try to change it decimals.

These topics caught my attention...
Trying to get XML driver to work with my WeeWX controlled Davis Station...
I have done simple XML file to put real time data in XML format, but maybe the format is not right?
Here is to file: https://kauttua.net/rss.xml
I guess it's in rss format still, any hints anybody?

General Weather Discussion / New experimental river data and forecast website from NWS
« Last post by elagache on February 17, 2024, 09:48:34 PM »
Dear WeatherCat observers of precipitation,

We have been getting a lot of rain in California and the rivers are starting get more than they can handle.  Just in time, the National Weather Service is testing a new system to provide river flooding data and forecasts.  It is called the New Enhanced River Forecast Pages.  There is a description here:

https://www.weather.gov/owp/operations

Here is the actual website URL:

https://preview.water.noaa.gov/

By default it will display the whole country.  You can then use the search feature to get a more local report.  However, it only recognizes river names.  There is a prefix you can use to bring up some city names.  If you put the prefix wfo: into the search field it will give you a list of some cities for which it has data.  However, I couldn't get it to include the city from which I learned about the site: Sacramento.  There is more information on this website on the Sacramento National Weather Service website:

https://www.weather.gov/sto/NWPSWebpage

It clearly is experimental and will undoubtedly improve, but it is already interesting.  Hopefully California won't need the site soon, but given the forecast - it might!

The last piece, and what I came back to ask, is about rain. Right now I have it just providing a rain year to date value, which is currently 24". WC seems to be interpreting that fine, but it's a little funny looking and seeing that number. Should I flip that to rain today ([rain0total-daysum])? I think this is how WC previously handled it when it was talking directly to my davis rather than through meteobridge.

I don’t know. WC hypothetically could detect a daily rain measurement, but if it’s working now, then I would just leave it alone. That XML seems pretty rigid. Let WC handle the gory details  ;-)

The <weathercat> piece is so it would validate as XML. =) without it (no parent element) it wouldn't validate.

Good to know about 0 vs null. I'll see about that. Right now it seems to be interpreting null and 0 as the same, and the errors have gone away and those channels now validate as valid. Meteobridge CAN report that info, but the Vantage Vue (my weather station) doesn't have UV/Solar. =)
