This page is a means of communication and repository of information for the upcoming biogenic aerosol field study at the Manitou Experimental Forest Observatory near Colorado Springs, CO, in Summer 2011.

Scientific Objectives

BEACHON-RoMBAS is a component of the overall BEACHON project and stands for "Bio-hydro-atmosphere interactions of Energy, Aerosols, Carbon, H2O, Organics & Nitrogen - Rocky Mountain Biogenic Aerosol Study." The scientific foci of the BEACHON-RoMBAS field experiment include the emissions of primary biological particles (PBAP) and secondary organic aerosol (SOA) precursors, and their transformations and impacts in the atmosphere. An important angle is the evaluation of the importance of water availability in those emissions, transformations, and impacts.

Archived Data

  • Data from BEACHON-RoMBAS and other campaigns and measurements at BEACHON are archived here.
  • Reference: Ortega, John V., et al. 2017. Manitou Experimental Forest Observatory Field Campaign. UCAR/NCAR - Atmospheric Chemistry Observations and Modeling. Accessed on [date]

Practical Organization

  • A List of Instrumentation including power and space needs has been compiled. (If you want to participate or add instrumentation which is not currently listed, please let us know). We have recently recruited two PBAP instruments from Europe as well as other collaborators on SOA and other measurements.
    • As a reference, the list of instrumentation for the BEACHON-ROCS-2010 field study is here.
  • Final dates: Jul-15-Aug 30, 2011

Logistics During the Campaign

All logistical information is centralized on the BEACHON-RoMBAS Logistics Page.

Real-Time Data and Model Output

  • Access recent met and gas data here.
    • The links "MET data" and "Chemistry Tower" go to real-time plots of the met data (from a small met station at the top of the tower and winds from the sonic anemometer) and some chemical species (O3, SO2, etc.) for the past few days. These are not "final" concentrations - they are just ones we calculated using some reasonable estimates of calibration coefficients (and some include calibration periods), but they give a good relative measure of what's happening.
  • Information on historic met/gas observations including diurnal cycles and wind roses can be found on the logistics page (see link above).

Data Policy

From previous experience, it is important to share data early to identify instrument problems, early findings etc. We would like to propose the following data policy, which is based on that from MILAGRO, CalNex and other large field campaigns. Please let us know of any suggestions for changes etc.

(a) Data will be shared during the field phase as soon as it is available (if possible the next day after it is taken for continuous instruments). An FTP site has been set up by NCAR for this purpose (see logistics page for details on formatting/datastatus/upload/download here). This is done with the understanding that data is not fully calibrated/corrected/etc., and its main use is to look at trends and start to identify patterns and correlations. Field data from other groups can only be used by people participating in the campaign, and CANNOT be shown or shared with people outside the campaign unless you have the permission of the data owners.

(b) Data should also be made available to all participants during the data analysis phase. Data from other groups cannot be used in presentations or publications without the permission of the data owners, and coauthorship should be offered to the data producers (which are then free to accept or decline the offer).

Data Analysis Meeting

  • Date: November 12-13, 2012
  • Location:
    • Center Green: CG1-1214 North Auditorium
    • 3080 Center Green Drive, Boulder CO
    • Not at Foothills Lab: CG is located on west side of Foothills Pkwy from NCAR Foothills lab. Take first right off of Valmont if coming from Foothills Pkwy onto Center Green Dr.)
