(pronounced ivy rocks)
Access to the IV-ROCS system is
Below is the reporting menu that is 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, no spaces or dashes, and verify the read back.
3) Enter your observation time using 4 digits or military time (example 7am = 0700, 2 pm = 1400)
4) Enter your data. The IV-ROCS voice will prompt Observers for the 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 stage.
If you report temperature data enter it by following the voice prompts. Each entry is followed by a # sign. ie: a maximum temperature of 65 is entered as 65# Negative values are preceded with a * ie: -15 is entered *15# (if your data is missing just enter a # sign.)
Enter your precipitation amount or melted snow amount to the nearest hundredth of an inch followed by a # (example: 0.01 is entered as 01#)
If you have snowfall enter it to the nearest tenth of an inch followed by a # sign. (example: 0.1 is entered as 1#) again do not enter the decimal. (1.0 inch of snow would be entered as 10# ) Other examples:
2.4 inches is entered 24#
10.2 inches is entered 102#
(if your data is missing just enter a # sign.)
If you have snow on the ground enter it to the nearest whole inch followed by a # sign. (example 1.2 inches is entered as 1# or 1.6 inches is entered as 2# or 11.2 is entered 11# ) (if your data is missing enter # )
For trace amounts of precipitation, snowfall or snowdepth use a * symbol.
Note: No decimal points are entered…iv-rocs will add the decimal for you in the right place. After you make your entry the voice will read it back to you…if it is not correct enter 2 and try it again. (if your data is missing just enter a # sign.)
After entering a precipitation value the voice will ask you to report the type of precipitation. You may report as many types as needed. If you have a mix of frozen, freezing and liquid precipitation always enter the them in that order. Liquid should always be last and snow must always be first.
The precipitation types and codes are as follows:
