Data Sharing Policy: AMAZE-08 is an LBA-approved experiment. AMAZE-08 participants agree to follow the LBA data sharing and publication policy as well as the fair use policy for LBA data. All data must be deposited in Brazil by law. Paulo Artaxo maintains an ftp server for this purpose. 

 

Publications Procedure: Based on the experience of past Brazil experiments (CLAIRE, EUSTACH, ABLE, and so on) as communicated by M. Andreae and P. Artaxo, all manuscripts should be sent to AMAZE-08 coordinators Scot Martin and Paulo Artaxo prior to submission. The coordinators will check that no deserving co-authors have been unintendedly omitted and that publications from one group are not saying things in direct contradiction to publications from other groups, without some opportunity for the two groups to communicate and think about some reconciliation of perspectives. These procedures will ensure that the LBA data sharing and publication policy is followed.

 

Clarification of 9 April 2009: If the words "AMAZE-08" appear anywhere in a manuscript, a copy of that manuscript should be sent to the coordinators (i.e., Scot Martin and Paulo Artaxo). Publications can be classified as primary or secondary use of AMAZE-08 data, but even in the case of secondary use, AMAZE'rs should have an opportunity to be aware prior to seeing in the published literature (i.e., the titles should appears under "manuscript drafts" on this webpage (see further below).

 

Instructions for ACP special issue. Special issue entitled "Amazonian Aerosol Characterization Experiment 2008 (AMAZE-08)." The guest editors are H. Coe, R. Cohen, A. Goldstein, and J. Schneider. Authors can submit their contributions by using the online registration form on the ACP website: http://www.atmospheric-chemistry-and-physics.net/submission/manuscript_submission.html. During the registration process it is important that the correct special issue is chosen.  Link to special issue.

 

Data available without password protection

1. TERRA and AQUA aerosol optical properties and cloud coverage over research site

 

Shown are the MODIS/Terra and MODIS/Aqua level 1 radiance data and level 2 aerosol/cloud products over a 6 by 6 degree^2 area centered over the AMAZE-08 research site (denoted as the pink circle in the image) since 10 Jan 2008. The visible image is at 500 m resolution. Aerosol optical depth, cloud optical depth, cloud effective radius, and cloud water path are retrieved at the spatial resolution  of 10 km, 1km, 1km, and 1km, respectively.

2. LIDAR observations.

 

All data are preliminary. You will find the last measurements and a archive. Five different plots show the temporal evolution of the range-corrected signal (arbitrary units) at 355, 532 and 1064 nm. The 355-depol plot shows the ratio of the depolarization signal and the total signal at 355 nm. In the four above mentioned plots the temporal and spatial resolution is 30 sec and 30 m, respectively. The 532-analog plot shows the range-corrected signal at 532 nm, but with a temporal and spatial resolution of 10 sec and 7.5 m, respectively. Measurements taken before January 2008 were performed in Leipzig, while the current location of the lidar is at the Silvicultura Site near Manaus, Brazil.

1. Regional model predictions of gases and PM as well as back trajectories for each day of experiment.

 

The numerical products are 48-hours forecast of atmospheric fields, carbon monoxide from biomass burning/anthropogenic sources, and PM2.5 from biomass burning. The products are generated by CATT-BRAMS model. Also included are 48 hours backward trajectories arriving around the site and at 7 vertical levels (0.5, 1, 1.5, 2, 3, 4 and 5 km above terrain). There is a link to near real time GOES 10 images and products.
