Learn More: Real Time Weather

Real-time weather data is data that is collected at 15-minute intervals from weather stations located at specific sites around Seminole County. A number of different weather parameters are being sampled by the instruments including current temperature (in Fahrenheit and Celsius), wind speed, wind direction, relative humidity, rainfall, ultraviolet index, dew point, barometric pressure, heat index, and, wind chill. This information is then posted to the Internet providing the user with weather readings that are typically delayed by approximately 15 minutes.

Real-time weather stations are located in seven different watersheds throughout Seminole County. The Davis Vantage Pro instruments are appropriately mounted to reduce data errors and are designed to measure not only rainfall but also a number of other weather paratmeters (listed above). A short archive of recent readings is presented in graphical form so that weather readings for the past 2 days can be accessed by clicking on the "2 Day Graph" button. Archived weather data from the sites for previous weeks, months (and eventually, years) can be accessed by selecting the "View data for a specific period of record" link. This record provides information beyond the "real-time" data including the daily high temperature, daily low temperature, dewpoint, highest windspeed, Temperature/Humidity/Wind index, solar radition, solar energy, ultraviolet radiation high reading for the day, heating days, cooling days and other weather information.

N/A

The near real-time weather data presented on the Seminole Watershed Atlas undergo a series of transfers before becoming publicly available and there can sometimes be a time delay in presenting the data. However, usually these data are presented within 15 minute intervals but is important to check the date and time of the reading. A caveat of using near-real time data is the possibility of error. Near-real time has not undergone as many quality control procedures common to our other data sets. Therefore, occasionally due to equipment malfunction there may exist errors within the data. Every attempt is being made to mitigate these errors before they occur.
