About Climate Perspectives
These products were developed for the Southeast Regional Climate Center at the NC State Climate Office.
Station data is prepopulated daily since early 2010, and each day's data will be kept for a full year. The end of every month will be kept, as well

A publication for the American Meteorological Society's 2011 Annual Meeting will soon be available:
Climate Perspectives: A New Tool for Real-Time Monitoring of the Climate across the Southeastern U.S

Description
Ranks a period of observations against:

How to Use

  1. Choose your date.
  2. Select a predefined city to automatically load. Or, choose another location using the map (double-click) or address bar.
  3. Select the station closest to the location provided.
  4. Update the display

Station Calculations
Station data is recorded for every day according to its observation time. An exception to this is the following:
COOP Stations with observation times between 12:30a and 11:30a:

Temperature values are computed and compared to the tenth degree in °C, then converted to °F.
Precipitation is computed and compared to the hundredth of an inch.

Station Data
Station results are returned in °F for temperature, and inches for precipitation.
Data percentage is the total number of daily observations that existed in the time period. Any codes that follow this percentage reflect:

Streaks and Threshold Perspectives
http://www.sercc.com/thresholds

Description
Threshold Perspectives:
The number of days that meet a given threshold for a period are displayed. These values are also ranked versus the same station's history for each period. The difference in the period and historical averages for the threshold is also shown.
Streak Perspectives:
The number of consecutive days that meet a given threshold for a period are displayed. These values are also ranked versus the same station's history for each period. The difference in the period and historical averages for the threshold is also shown.

How to Use

  1. Choose your date.
  2. Select a predefined city to automatically load. Or, choose another location using the map (double-click) or address bar.
  3. Select the station closest to the location provided.
  4. Determine the variable to use.
  5. Update the display

Station Calculations
Station data is recorded for every day according to its observation time. An exception to this is the following:
COOP Stations with observation times between 12:30a and 11:30a:

Temperature thresholds are computed and compared to the thousandth of a degree °C, then converted to °F.
Precipitation thresholds are computed and compared to the hundredth of an inch.

As of May 13, 2015 the threshold 85F was added. This will not be available for dates before this time period.
