Main content

Atmospheric rivers (ARs) are an important component of the hydrological cycle and have been increasingly  recognized as critical to Antarctic meteorology and climatology. Since just 2014, atmospheric rivers have been identified as a sub-tropical link to the Antarctic continent and create extreme atmospheric conditions that are largely consequential to surface melt, snowfall, and ice-shelf stability.

The goals of this workshop include reviewing  the current state of knowledge, identifying research gaps and emerging science, as well as actively beginning a review paper.  Specific science categories include tools, dynamics, impacts, energy and moisture budgets,  climate change and variability, and cross polar themes.

Arriving from the Airport

Denver International Airport (DIA) is 45 miles from NCAR and there are several ways to arrive.

The AB bus (westbound to NCAR) is the least expensive option. It leaves the airport every half hour (see schedule) and stops throughout Boulder. GoogleMaps, on your phone or computer, also has up to the minute bus scheduling information.

RTD’s website will also help you plan your travel by bus to destinations throughout the Boulder region (including Longmont, Louisville, Lafayette, Superior, etc.) and to Denver International Airport. RTD Trip Planner.

Eight Black is a shuttle service from DIA. Major credit cards are accepted and it is highly recommended that you make a reservation.

People also use Lyft and Uber from the airport to Boulder, this can be expensive.

Getting around Boulder

B-Cycle is a non-profit bike-sharing app that you can use to rent bikes from the 41 stations around town.

Lime has e-scooters for rent in East Boulder and must be ridden on multi-use paths and bike lanes.

HOP is useful for getting around to the city's most popular attractions and arrives every 7-15 minutes.

More information can be found on the City of Boulder website.

The Weather

Coloradans like to say, “if you’re tired of the weather, wait 20 minutes.”

The weather can change without notice and it is good to be prepared. Dress in layers and have rain gear in your backpack when hiking. Summer can bring very hot and dry weather with afternoon or evening showers. It is usually cool at night and sweaters can be necessary when hiking, especially at a higher elevation. In addition, thunderstorms are common in the summer as well.

Boulder is 5,430 feet (1,655 meters) above sea level. At this elevation, it is important to stay hydrated and wear sunscreen and sunglasses. If you are coming from a lower elevation, it is likely that you will notice the effect of the altitude. Some people experience headaches, dizziness, shortness of breath, nausea, and general fatigue. It is advised to drink plenty of water, especially in the week leading up to arrival.
