Interactive Voice - Remote Observation Collection System
A new Cooperative Program data acquisition system, (IV-ROCS), is now
available for use. You simply dial a designated phone number, and
IV-ROCS voice will direct you through the data entry process.
IV-ROCS will be used as the replacement for the ROSA reporting system
that is being used by some observers. If you are a NWS cooperative
observer using a ROSA telephone, you may start using IV-ROCS at any
time. NWS representatives will demonstrate the IV-ROCS voice
system to observers during this fall and winter as we make our station
You can call or email Mark Ewens, the Data
Acquisition Program Manager for more information.

Below is a sample of the reporting menu that will be used with IV-ROCS.
1) Select the language.
When asked, enter 1 for English or 2 for Spanish
2) Identify yourself.
Enter your 6 digit station number (beginning with '21' if you live in
Minnesota, or '32' if you live in North Dakota) and verify the read back.
3) Enter your data. The
IV-ROCS voice will ask you for your data. You will only be asked
to provide data that your station is equipped to provide.
Observation elements IV-ROCS is capable of recording are: precipitation
(including snow), temperature, evaporation, soil temperature and river
1) Key-ahead. The system
has a key-ahead feature. As soon as you become familiar with the
data entry scripts you can key-ahead quickly to speed your data
entry. When you verify or key-ahead the system will stop the
script and move to the next script. It is recommended that an
observer not use the key-ahead feature until after the data is repeated
to verify the accuracy of the data.
2) Entry Verification.
Enter a # after each entry to let the system know you are done.
The IV-ROCS voice will then read back your entry and ask for
verification. Enter 1 if the entry is correct or 2 if
you need to make a correction. You do not need to enter the #
after the data verification entry.
3) Special Characters.
Enter precipitation values without a decimal point. The IV-ROCS
will insert the decimal point at the proper place and read the value
back to you. Please remember that rain is entered to the nearest
0.01, snowfall is entered to the nearest 0.1 and snow depth is entered
to the nearest inch. To report a trace of precipitation you can
use the * key on your telephone pad. The * is also used to
indicate a negative temperature.
4) Precipitation Types.
The IV-ROCS voice will ask you to report a precipitation type after you
enter a precipitation amount. You can report as many
precipitation types as needed. The precipitation types and their
5) Email Notification. If
you need your NWS representative to contact you the IV-ROCS will send
an e-mail to the local office requesting that they give you a
call. Due to work schedules, it may be a couple of days before
you are contacted. The final script of the session will ask if
you need to be contacted. Enter 1 if you want to be
contacted or simple hang-up if you do not.
