What is measuring in Puerto Rico

196 instruments still reporting in Puerto Rico, across 5 networks, each one with the kind of measurement it makes and how often it makes it. Open a place below to see which of them stand near it.

measured now26 instruments

Data-collection platforms

15 instruments/hourly

temp, wind, gust, humidity, pressure

Shore stations, fire weather stations and river gauges on one identifier. Most of them measure the river and are never offered here; the ones that are published air temperature and wind. A platform that was quiet when the catalogue was built is still listed, because it remains registered with its network. It is the only shoreline wind this service carries.

Airport surface observations

6 instruments/minutes

temp, wind, gust, visibility, precip, pressure

The backbone. Individual sensors fail and the station does not, so every reading is published with the age of the observation beside it.

Soil climate stations

5 instruments/hourly

temp, humidity, soil temp, soil moisture

Air and soil together: temperature and moisture measured in the ground at depth, hourly, mostly on farms and research land.

measured daily170 instruments

Volunteer precipitation and snow observers

139 instruments/once a day

precip, snowfall, snow depth

The same measurement a cooperative observer makes, from many more gardens. Puerto Rico publishes 139 of these against 31 cooperative observers, so on most days it is the densest picture of what is on the ground that exists.

Cooperative observers

snowfall, snow depth, precip, high, low

A person, a board and a ruler, in the morning. It cannot say what is falling right now and it is the best answer to how much is on the ground.
