UK SOLAS Project: Dust Outflow and Deposition to Ocean (DODO)

Introduction

The Dust Outflow and Deposition to Ocean (DODO) project is a UK SOLAS project which also has links with the DABEX and AMMA projects.

Case studies will be conducted using in situ measurements made by the FAAM BAe-146 aircraft to predict dust deposition to the northern hemisphere Atlantic Ocean. These studies will describe how changing chemical and physical properties in the dust affect its long range transport and will assess the radiative impact of the dust and its effect on sea surface temperatures in nutrient rich waters of the Atlantic Ocean. The dust sources will be fingerprinted using single particle characterisation and by assessing their main composition. The climatological representativeness of the studies will be assessed and used to predict the seasonal footprint of dust deposition to the north Atlantic Ocean.

Availability of data

Some DODO data are publicly available while other data are restricted. Data collected onboard the FAAM BAe-146 aircraft are split into core data and non-core data and a definition of those instruments that are part of the core suite is given on the FAAM Instruments page.

• Processed core data collected on board the FAAM aircraft are public access but require application.
• Raw core data collected on board the FAAM aircraft are restricted to FAAM staff and scientists involved in test flights.
• Access to all other DODO data is restricted to DODO participants for a period of one year following the end of the data set collection, as per the UK SOLAS Conditions of Use. Following this period, there is a further year of restriction to SOLAS participants. Data will then be made public but requirements will continue to apply to publications based on DODO data.
• It has been agreed that participants in the DABEX and AMMA campaigns can also have access to the data, but it is still necessary to register for DODO in order to accept the DODO conditions of use which are different to those in the co-operating programmes.
• It has been agreed that DODO participants can also access data from the DABEX and AMMA campaigns.

Access to data

(1) Access restrictions

If you wish to apply for access to the various sections of the DODO archive, please follow the guidelines below.

1. Register as a BADC user — if you are already a registered BADC user, skip this step; if you have forgotten your BADC user ID and/or password, please contact the BADC helpdesk at badc@rl.ac.uk;
2. Apply for access to
   • FAAM processed core data (public) — you will be asked to abide by the FAAM Core Data Conditions of Use.
   • FAAM raw core data (reserved to FAAM staff and scientists involved in test flights) — you will be asked to abide by the FAAM Test Flight Data Conditions of Use.
   • All other DODO data are now public — All users are requested to acknowledge the data providers in any publication based on DODO data.

     An agreement is also in place to give DODO participants access to data from the related AMMA and DABEX campaigns. Please refer to the dataset web pages for details on how to gain access and mention DODO participation in your application. Similarly, AMMA and DABEX participants can gain access to DODO data. Please mention you are a participant of these projects when registering.

(2) Where to find the data

Data and documentation supplied to the BADC by the project team are stored in the DODO archive, from where they can be viewed and downloaded by authorised users.

Data format - File names

• Non-FAAM data and FAAM non-core data are formatted in NASA Ames.

• FAAM processed core data are formatted in NetCDF.

• FAAM raw core data are stored in zipped VMS files.
