I have always been a weather enthusiast and have even done some work for the Oregon State Climatologist many years ago. This site is a development of that passion. Many times I've wanted to get some quick weather statistics or data and it's in a lot of different places or in a variety of formats. Trying to just get some simple information can turn into quite a chore sometimes. That's where this idea was born. It's a place I can start collecting weather data from a variety of sources and store it in one consistent format and generate a variety of statistics and reports with the data.

Knowing that I desired this information, I felt there are probably other enthusiasts that also do. I built this site not just for myself, but for all those other weather nerds out there too. Not only can someone browse the data and reports, I will allow them to upload and maintain their own weather data which they can choose to share or not.

While the site is currently designed for only U.S. stations, I do plan on changing it for international use in the future. In the meantime I hope you enjoy this site, and if you have any question, comments, complaints, or wonderful praise, you can reach me by clicking the Contact Me link at the bottom of my personal website at https://www.mikekrejci.com.

The data for this site comes from several sources and while as much attention as possible is given to accuracy, there is no guarantee that the data on this site is complete or accurate. If you find missing, or incorrect data, please, use the contact me form and let me know so that I can correct it. Also, some of the data from this site comes from individual user information, in those cases, I can not make any type of statement on it's reliability. If someone is knowingly posting bad data, I will remove it, but beyond that, it will stand as they enter it. When viewing a station page, it will clearly indicate the source, or sources, of data for them.

Most of the stations on this site are from the National Weather Service which generates data for each of them on a regular basis. Generally at least every day, and in some cases far more frequently. This site pulls that data 6 times a day, or once every 4 hours, and will update the database with any new data that has come in. These stations are generally identified by a three letter code when looking on the maps, or station lists. User entered stations will have unknown update frequencies, and are identified by the code of USER on the map and station lists.

Daily Climate Reports (CLI) from National Weather Service

The NWS generates a new CLI report for each station several times a day. These reports list various observations and their times and is the main report I use to collect the daily updates. These are the reports that are pulled every 4 hours for all of the NWS stations.

Preliminary Monthly Climate Data (CF6) from National Weather Service

These reports are another set of reports that are generated by the NWS each day. They do not list as much information as the CLI reports but have information for each day of the month being pulled. I pull and process these reports once a day and will update the database from their data where a CLI report did not get produced or had missing data.

Preliminary Monthly Climate Data from National Centers for Environmental Information

This is NOAA's site for the storage of a vast number of global climate records. For all of the stations in which it is available, I have downloaded the past data from this site and loaded it into the database. There are some stations in which this is the only source of information I have, and are therefore listed as user stations and updated manually be me whenever a new dataset is available for that station. There is no regular schedule for these updates.
