NOAA Regional Climate Centers
NOAA's Regional Climate Centers (RCCs) are a federal-state cooperative effort. The RCC Program is managed by the NOAA National Climatic Data Center (NCDC). The six centers that comprise the RCC Program are engaged in the timely production and delivery of useful climate data, information and knowledge for decision-makers and other users at the local, state, regional and national levels.

American Association of State Climatologists
The AASC is a professional scientific organization comprised of state climatologists (one per state), directors of the six Regional Climate Centers and associate members who are persons interested in the goals and activities of the Association.
To visit a State Climatology Office, click on the map (left) for that state's office, or visit the AASC website.
NOAA National Climatic Data Center
NOAA's National Climatic Data Center (NCDC) maintains the world's largest climate data archive and provides climatological services and data to every sector of the United States economy and to users worldwide. Records in the archive range from paleoclimatic data to centuries-old journals to data less than an hour old. The Center's mission is to preserve these data and make them available to the public, business, industry, government, and researchers.
NWS Climate Prediction Center
The National Weather Service's Climate Prediction Center (CPC) produces operational predictions of climate variability, real-time monitoring of climate and the required databases, and assessments of the origins of major climate anomalies. Monthly, seasonal, and long-lead (out to 13 months) outlooks can be found here.
National Drought Mitigation Center
The NDMC monitors drought in the U.S. and provides information on drought and its impacts to state, federal, regional and tribal governments that are involved in drought and water supply planning. The U.S. Drought Monitor is produced at the NDMC.
National Integrated Drought Information System (NIDIS)
This is a portal for national drought information, planning, research, impacts, education and climate conditions, including links to state and regional conditions.
USDA National Water & Climate Center
The NWCC is part of the Natural Resources Conservation Service, U.S. Department of Agriculture. The mission of the NWCC is to lead the development and transfer of water and climate information and technology that support natural resource conservation.
NOAA El Niño Theme Page
A very comprehensive site on El Niño and La Niña. In addition to excellent descriptions of these phenomena, this site includes current conditions, forecasts, data, and a lot of nice graphics.
MRCC Climate Watch
Climate maps, narratives, and other resources developed by the Midwestern Regional Climate Center. The Climate Watch page is your portal for Midwest and Central region temperature, precipitation, soil moisture, and growing degree day maps in daily, weekly and monthly formats. Also available are maps and information for regional and national drought conditions.
You can find weekly and monthly climate highlight narratives, as well as a tool to search past events from the highlights back to 2000.
Great Lakes Water Level Dashboard
Developed by NOAA's Great Lakes Environmental Research Laboratory (GLERL) with support from the Great Lakes Restoration Initiative, and in cooperation with the Cooperative Institute for Limnology and Ecosystem Research, this is an interactive tool designed to facilitate visualization, analysis and downloading of Great Lakes water levels and forecasts on a variety of time scales.
Several paleological reconstruction data sets using submerged tree stumps and tree ring data to draw conclusions about past lake levels have been added to the dashboard. In addition, lake level projection data sets from some recent regional climate modeling studies were made available. Both of these types of data sets can add context to our understanding of current lake level fluctuations as well as out attempts to project how future climates will impact these levels.
NOAA's Global Climate Dashboard
Just as the dashboard of a car gives you a quick look at the status of your vehicle, this tool gives you a quick look at the status of Earth's climate system (scroll to the bottom of the page to access the dashboard). The interactive graphs let you explore climate-relevant measurements and the relationships among them for different time periods. The climate-relevant measurements you can explore include global temperature, carbon dioxide, sea level, Arctic sea ice, spring snow cover, ocean heat, sun's energy, glaciers, and annual greenhouse gas index. You can also explore variables related to climate variability (e.g. El Niño/La Niña Index and Arctic Oscillation) and modeled climate projections.
NCDC State of the Climate
The National Climatic Data Center prepares an extensive report each month detailing the State of the Climate both globally and nationally. The reports are made available about a week into the following month and cover everything from wildfires to snow and ice to hurricanes and tropical storms, among others. Significant events are noted and temperature and precipitation are ranked for various scales from global to national to state, and even down to climate division. Rankings for the past month, season, and year are all available. The Regional Climate Centers each contribute reports for their own areas describing the recent climate and highlighting significant events.
Weather On Your Birthday
What was the weather on the day you were born? MRCC has created a tool to find the daily weather report for your birthday. Enter your birthdate, choose the location, and you will see the daily weather reported for that date and location.
NCDC Storm Events Database
The NCDC Storm Events Database contains various types of storm reports. Data are available as a searchable web interface, or download in comma-separated files (CSV) from October 2006 to present, as entered by NOAA's National Weather Service (NWS). The entire Storm Events Database (1950-present) is available as a Microsoft Access database.
NCDC Extreme Events U.S. Records
Extreme events such as heat waves, droughts, tornadoes, and hurricanes have affected the United States since the dawn of time. NCDC provides a variety of information detailing these events, categorized by type of event.
The U.S. tool lists and maps records tied or broken on a given date for weather stations across the 50 United States. Records are distinguished as daily, monthly or all-time (largest/smallest value ever observed at that station). Summary information for recent periods (year-to-date, month-to-date, last 30 days) is provided in tabular format.
MRCC Climate Watch
Climate maps and other resources developed by the Midwestern Regional Climate Center. The Climate Watch page is your portal for Midwest and Central region temperature, precipitation, soil moisture, and growing degree day maps in daily, weekly and monthly formats. Also available are maps and information for regional and national drought conditions.
You can find weekly and monthly climate highlight narratives, as well as a tool to search past events from the highlights back to 2000.
SERCC Climate Perspectives
The Sourtheast Regional Climate Center has developed a highly informational, at-a-glance web mapping and data summary tool. The tool provides daily surface weather information and puts the data into geographical and historical climate perspectives. Streaks, thresholds and ranks are among the climate perspectives that this tool offers for individual stations displayed on regional maps. Our pages default for the Midwest, but you can see information for the entire U.S. by visiting the Southeast Regional Climate Center pages.
USDA Evaporative Stress Index
The Evaporative Stress Index (ESI), available from the Agricultural Research Service at USDA, describes temporal anomalies in evapotranspiration (ET), highlighting areas with anomalously high or low rates of water use across the land surface. Here, ET is retrieved via energy balance using remotely sensed land-surface temperature (LST) time-change signals. LST is a fast-response variable, providing proxy information regarding rapidly evolving surface soil moisture and crop stress conditions at relatively high spatial resolution.
CoCoRaHS Water Balance Charts
Water Balance charts are now available for selected locations in the U.S. thanks to the Community Collaborative Rain, Hail and Snow network (CoCoRaHS) at Colorado State University. Daily precipitation and grass-reference evapotranspiration (ETo) are currently monitored and reported by volunteers at over 100 locations in the U.S. The charts simply show the difference between accumulated precipitation and accumulated evapotranspiration, making it very easy to visualize the onset and continuation of drought as well as drought recovery.
