Current vs. 20th Century Baseline
Temperature
Current (2024) monthly climate data (solid) compared to historic climate baselines (left). Climate baselines include minimum and maximum (light grey), 95% distribution (grey), and middle 50% distribution (dark grey) of values recorded from 1901 to 2000, along with the baseline average (black line). Monthly deviations from historic baselines (right) in 2024 with positive (red) bars indicating above average deviations, and negative (blue) bars indicating below average deviations. Historic baselines are based on NOAA 20th century normals for a given park’s geographic centroid. Current monthly data are derived from NOAA NClimGrid gridded climate dataset extracted for a given park’s geographic centroid.

About the Data
Background
The Northeast Temperate Network (NETN) helps its 13 member parks better
understand the health of their biological communities (forests, birds,
etc), waters, and other natural resources through long-term monitoring
and periodic inventories. Our mission is to collect, manage, and
translate high quality information about the condition of natural
resources so that our national parks can make better-informed management
decisions. This information is also valuable for supporting research
projects, providing educational opportunities, and promoting better
public understanding of park natural resources.
The Northeast
Temperate Network is one of 32 Inventory & Monitoring networks
across the country that are developing a strong scientific foundation
for stewardship and management of natural resources throughout the
National Park System. In this way, we help fulfill the National Park
Service’s mission of conserving our national treasures for future
generations.

About the Data
The climate summaries rely primarily on monthly gridded climate data
downloaded directly from NOAA’s National Centers for Environmental
Information (www.ncei.noaa.gov) and
extracted using the centroid of each NETN park. The climate metrics
derived from the NOAA gridded climate data in this summary are total
monthly precipitation (in), average monthly maximum temperature (F),
average monthly minimum temperature (F), and average temperature (F).
Historic baselines (aka normals) are also derived from NOAA gridded
normals for the same park centroid. This summary uses the 20th century
normal (1901 to 2020).
Drought conditions are derived from the
U.S. Drought Monitor
(https://droughtmonitor.unl.edu/),
which reports proportion of counties that are in one of five drought
levels every week. This summary reports drought conditions for the
predominant county that each park occurs in. Note that because parks are
typically much smaller than the county they occur in, reported drought
conditions may not always be the most representative of conditions on
the ground.
Climate data are compiled and visualized using
functions in the
climateNETN R
package. See
https://katemmiller.github.io/waterNETN/
(user guide for both waterNETN and climateNETN R packages) for details
on how to use the functions in this package. Note that, among other
features, you can use the 30-year normal instead of the 20th century
normal as the baseline, can use scientific units (e.g., F and mm), and
can change color palettes and year ranges in plots within climateNETN
functions.
