There are some new data viewing tools provided by the National Weather Service that offer different ways of viewing weather and climate data, including data from CoCoRaHS. Many of them obtain their data from the Applied Climate Information System (ACIS) developed and maintained by the Regional Climate Centers (RCCs). The daily data from CoCoRaHS are fed into ACIS by the Global Historical Climate Network (GHCN) Daily database which is collected, compiled, and distributed by the National Climatic Data Center in Asheville, NC.
The GHCN database only contains the data for CoCoRaHS stations that have submitted at least 100 observations. New active stations are added to the GHCN database once a month, so depending on timing it could be four months before a new station appears in GHCN, and thus in the products listed below. *Please note: the underlying database for the NOWData tool does not assimilate the multi-day amounts, so days included in a multi-day period are set to "M". This should be resolved in the future, but in the meantime, you can use the Station Precip Summary option on the CoCoRaHS web site to get your actual monthly totals.
Links to the various products are below, but finding your CoCoRaHS data are not necessarily intuitive. We encourage you to follow the directions provided below each product:
Click here and begin by selecting your nearest National Weather Service Office page. Once you select your nearest office, you will land on the NOWData page for your area. Here, you will need to click on 'View Map' under 'Location' where you can then select 'Show More Stations' using the link below the map. From here, you will see several CoCoRaHS icons appear, and now you can zoom in and click on your station. Once your station is selected, choose an product such as 'Monthly Summarized Data' or 'Accumulated Precipitation', choose an option and select 'Go' to view the data.
There are detailed instructions along with screenshots and images from NOWData on the CoCoRaHS Blog post here.
