We have programmed Degree to make the best of whatever data is available. because they were only set up recently), gaps and errors in their reporting, and less-than-ideal recording frequencies (for example, some only record the temperature every 6 hours or so, and some don't record at night).
But lesser stations may have shorter data histories (e.g. Many stations in our system have a long history of reporting frequent, regular, accurate temperature readings, from which we can calculate high-quality degree days going back a long time. The closest weather station isn't necessarily the best choice, because weather stations vary considerably in their data quality and coverage (the length of time covered by their historical records). Choosing the best weather station for location and accuracyĭegree calculates its degree days using temperature data from thousands upon thousands of weather stations worldwide. You might also want to find out why 5000+ energy professionals get data from here each month (and often a lot more frequently). If you are new to degree days, you might want to skip straight to the brief introduction at the bottom of this page. However, we suggest you read the tips below as they do cover some important points. If you are already experienced with degree days, you will probably find most of the options above to be self explanatory (the less-obvious regression options have separate instructions).
