Data is transmitted to the local NWS office. This near real-time data is used to support the
day-to-day operations of the NWS in its forecast and warning decisions.
The data supplied to the National Weather Service by Cooperative Observers is then sent to our
archive center, the National Climatic Data Center in Asheville, North Carolina.
The data is checked, archived and published for public review. The forms and charts sent in
each month are reviewed by personnel here at the local weather service office in Albany before being
submitted to the archive center. In the past the data was again reviewed and the information logged
into a computer by hand. Forms and charts are now electronically scanned with computers reading the
The computer then does the final checks, and compares the individual station data with
surrounding stations to ensure the data is within set tolerances. Data beyond these levels is
discarded by the computer. This process has been deemed the best practice to keep the data as
unbiased as possible. Human error and equipment problems are generally the culprit for erroneous
In an effort to help eliminate errors even further, we are incorporating new way's to log
station data. Computer spreadsheets are now available for observers to use which can then be emailed
to us at the end of each month.
As computers become more involved in reading the scanned forms, the legibility of the forms
becomes an increasingly important issue. Forms prepared by a computer and emailed have proven to be
easier to read, less mutilated by the postal service and received in a very timely manner.
The actual forms prepared by observers can now be viewed from the archive center. Data compiled
from the form can also be accessed and the published version of data for the entire state can also
