Here is the 150 year old (or so) weather station in my area (Prospect Reservoir):  It is pretty much the weather station that can be applicable for the (Western) Sydney region between Liverpool and Parramatta. Wow what a region-applicable weather station 😍 |

Riga's weather station on Jan 4th  Its location on the map: Fine UHI station athough it's unfortunately shaded by tree canopies. Rainfall is presumably measured along with sunshine on top of the uni building to the NW. |

Phoenix Airport (KPHX) ASOS. Primary climate site for the Phoenix metro area. Main sensor cluster:  Satellite view Less than 50 ft (15 m) from a paved surface, also right next to the embankment of the Salt River which probably has some local effects on the temperature.  Zoomed out  |

That station placement is pure comedy. Would have to be in the world's top 10 grand botev stations of all time. That taxiway turning off to the south of RWY 25L, aircraft are literally aiming their exhaust at the station, by the looks of it barely more than 100m away. And that's before we consider the acres of black concrete..... What a botev station oh my god.
Surely, surely there is a park somewhere in the vicinity of downtown that would be far more suitable for "Phoenix" temps.

I successfully sent weather data via satellite for the first time today. There is still a lot of design work left to do to reach the point where I have a functioning satellite weather station, but this will allow me to place a station anywhere on earth instead of being limited by cell coverage.
However, the global coverage comes with two main disadvantages: cost and data latency. The number of transmissions I can make is limited to once per hour with satellite, whereas I've configured my cellular weather stations to transmit as frequently as once every 5-15 minutes. It costs $5/month per station to send data via satellite, compared to about $0.80/month for cellular data at the same transmission frequency.
Another drawback is satellite coverage is not continuous. The weather station must wait until a satellite is overhead to transmit data, which can be up to several hours. You then have to wait for the satellite to relay the data back to earth, so data can never really be "live" unless the number of satellites in the constellation is increased dramatically. The coverage is quite a bit worse along the equator than in polar regions.

Archbold Biological Station  Air temperature is measured in the "Nimbus" multi-plate shield on the right. They're always mounted about a foot too low, but that 5 ft standard is pretty typical for all COOP stations. The low Stevenson screen shelter might have a grass temperature sensor or soil temperature sensor inside.  The site has towers with both an ultrasonic and cup anemometer, which wasn't turning at all on this calm, warm morning. Neither has data available to the public.  There are also three rain gauges: a standard manual gauge (which is the data submitted to NOAA), a tipping bucket gauge, and this giant weighing gauge.  The station is located at the bottom of this slope down from the nearby scrub area. It's also surrounded by vegetation on three sides, and a building on the other.  Firebreak with typical scrub vegetation nearby  A few hundred yards away is an AWS that actually reports to MADIS (albeit intermittently). The temps are roughly analogous to the COOP station, but slightly more moderated. It also seems to be offline whenever some dubious data appears for the COOP station.  |

Data from the calibration of my anemometer to determine the conversion factor from the wind cup radial speed to actual air speed. From what I've read, it seems this factor is somewhere between 2 and 3 but must be determined experimentally. I obviously don't have access to a wind tunnel to do a proper test, but I do have a car and and app to log speed based on GPS at regular intervals. I mounted the anemometer to the top of my car and compared the readings to the GPS-indicated speed. GPS isn't really all that accurate, but is good enough for my purposes, especially when it's not going to be mounted in a standard 10 m placement anyway. It shows a fairly linear trend, but I was mostly interested in the 20-30 mph range so that's where most of the readings are. This anemometer will be going on my station that I'm installing in Utah next week.  |

The Buenos Aires Observatory
  After seeing various pictures of other stations, I gotta be a bit more appreciative of this one...

I took this pic years ago when I had to go to work in that area. |
