Description
Climatological Data has existed in some form since 1890. While
this publication does include many locations, it does not include
all climatic stations for any given time. In some rare cases, there
are gaps in the archives available. Over the years that Climatological
Data has been produced, there have been changes, improvements, and
additions to the monthly publications. Also, the climatic stations
available today have not always been available for publication.
Sample PDFs
Over the years that Climatological Data has been published, the
format of the CD Publication has changed. There are three major formats
that you will find when reviewing archived CD Publications: the pre-River
Basin years of 1890 to June 1909, the River Basin years July 1909 to 1913,
and current CD Publications from 1913 to present day.
Pre- River Basin Year 1890 to June 1909.

These documents vary from state to state in the amount of
data. Here is an example of Colorado's Pre-River Basin Years.
It is important to note that not all states have
CD Publications during this time period. There are some gaps in
the reports that were created. The reported data varies
from state to state.

River Basin Year July 1909 to 1913.
|
| |
|
During the period of July 1909 until the end of 1913, the CD Publications were created for major River Basins
such as Mississippi. The information for a state may appear in several
River Basin CD Publications. To collect all the information for a
state like Colorado, four River Basin publications are needed. The
NCDC server will automatically provide customers with all the related
River Basin documents. This sample is one of the four publications
for Colorado.
