SEAC4RSGround and Ship MeasurementsJanuary 2012
NCAR
Surface Network Overview• Because of metrological complexity & political
sensitivities in SE Asia, data from a ground network is required to adequately cover the region.
• All SEAC4RS ground components of sun photometer, lidar, ozone and in situ measurements have field history in the region with established partners.
• There are few total “unknowns” but we expect the deployment to be fairly “fluid.” in nature.
• Also, there is still room to accommodate needs of the science team, including the deployment of additional instrumentation-particularly at supersites and at sea.
Ground Network Components and preliminary POCs
• AERONET/MAN: Brent Holben ([email protected] )– 20 Long term+7 Temporary– 3 ferry lines to be manned with microtops for MAN
• MPLNET: Judd Welton ([email protected] )– 4 Long term +5 Temporary sites. – NEIS in Thailand
• SHADOZ: Anne Thompson ([email protected])– 3 Long term+ 4/6 temporary*
• VASCO Jeffrey Reid and Haf Jonsson ([email protected] ).• Singapore Super Site: Jeffrey Reid ([email protected]) • Source sampling: Yokelson ([email protected] )• Other likely data collections:
– Puji Lesteri (IIT-Bandung), Bandung- Filter chemistry– Mastura Mahamud (UKM)-Filter Chemistry– BMG– GAW sites on Maylay Peninsula, Sabah, and Sumatra– Japanese sun photometer network?– Extensive Malaysian raobs

Airspace• Previous studies often
focused on VPs over ground sites.
• But both the political situation and clouds dictate that such profiles will be rare.
• Even the range circles are a “best estimate.
• Ground network is being developed to provide scale and “perspective” on airborne measurements.
• But, we may get lucky….

✗ International agreement not final
* Hong Kong group operates their own ALS lidar. They are not part of MPLNET due to current ban on bi-lateral NASA-China interactions.
MPLNET has exclusively used MPL instruments in past. Newer lidars from Leosphere (ALS model) are now accepted in MPLNET.• MPL: 527 or 532 nm, elastic backscatter lidar. Fully autonomous, 24/7 data. • ALS: 355 nm elastic backscatter lidar with depolarization capability. Autonomous, and 24/7 data where possible.• Standard network Level 1 data: 0000-2400 UTC, 0-30 km, 1 minute temporal and 75 m vertical resolutions.• MPL does good job of detecting thin cirrus in this region, we are still evaluating ALS performance but looks promising• NRT Data: available on website, 1 hour for some sites (still evaluating), next day for others

Maritime Aerosol Network as a Component of AERONET
• MAN represents an important strategic sampling initiative and ship-borne data acquisition complements island-based
AERONET measurements
Smirnov, A., B.N.Holben, D.M.Giles, et al., Maritime Aerosol Network as a component of AERONET – first results and comparison with global aerosol models and satellite retrievals, Atm.Meas.Tech., 4, 583–597, doi:10.5194/amt-4-583-2011, 2011.
In the last several years data acquisition was extended to
the areas that previously had very little or no coverage at all
MAN coverage-Oct 06 to Jan 2012
Singapore Supersite
• Lidar: MPL Lidar, maybe Wisc HSRL• Radiation: AERONET, Solar, IR, direct/diffuse solar• Aerosol: SMPS, 3l neph & PSAP, TEOM• Filters: Elemental (DRUM), ICPMS, Organics,
OC/BC gravimetery• Gas: O3, SO2, CO, NOx
• Other: All sky camera, time-lapse video, local weather
Roof and lab site on National University of Singapore campus. Easy to add equipment
Other site enhancements and measurements in the region.
• Solar flux radiometers will be added to several AERONET sites from GSFC and NRL.
• 2 others will have “direct diffuse” solar radiometers.
Enhancements
• 4 sites in Thailand have extensive radiation measurements as part of the Silpakorn University network.
• There are three global GAW sites in our domino, plus 9 “regional.” They have widely varying data collection protocols and efficiencies.
• Japanese SKYNET and a NEIS lidar in Phemai are also in the region, as is a lidar in Hong Kong.
• We may be able to get other filter measurements in the region.
Other measurements (Need to negotiate data access)
Yokelson Group Battery Powered Mobile FTIR
Gases: HCN, CO, CH4, CO2, NH3, NOx, HCl, NMHC, OVOCPM2.5: EC/OC, metals (filters can be added)
Brick Kilns
Trash Burning
Crop Residue Fires
Cooking Fires
Major Sources That Are Virtually Unstudied in Asia
Room for more.
• Generally we can get into key sites.• If other team members want to provide more
instruments, we can help get them in and maintained.
• There is also an opportunity for students for site staffing.
• We are light on gas measurements. More Blake cans?
Summary• We have the most extensive ground largely in place network
in the history of SE Asia.• Flight and weather restrictions imply the ground network is
largely for regional context. The AERONET sites in particular will be around for a while.
• SHADOZ will add three sites.• We have funding for a September cruise in Philippines water.• Singapore is a comprehensive supersite and easy to work
with.• Other source measurements may be made by Yokelson’s
group.• There are lots of other measurements being made in the
region, but access is not always straightforward.
