NON-EOS/ECS Topics

These are topics for PoDAG to discuss during the meeting (not necessarily right now)

• Historical “AWS” Climate Data• Melt On-set Data Set reprocessing• Sea Ice Motion Data Sets• SDO-EVE opportunity• Scatterometry Data Sets• F-10 SSM/I Wentz Tapes Status• Snow Water Equivalent Data Sets Page• HARA data updates • PARCA data sets


AWS Climate Data RecordsJulienne says …• I have been processing, or rather extracting from a NCDC data set all the historical

AWS data from the Arctic and Antarctic. This has been quite a task. I'm attaching here a listing of the NH data files, a figure showing their locations and some sample data to give you an example. What we would now like to do is make this an official DAAC data set.

• As part of this, we would really like to make a web interface where a user can click on the map that would bring up the stations and some information about them and then link them to ftp site where the data would reside. Ted was thinking that Jennifer could probably do something like this.

• I've already produced the data set, and I'll be doing most of the documentation. We'll need some additional writer support to help get the guide doc complete, announce the data set, etc., some ops time to stage the data, and some web development time (1 month of Jennifer's time for example).

• Questions to the DAAC (and to the UWG are: - do we make this an official DAAC data set? - do we set aside some DAAC resources to get this data set distributed.


AWS/Climate Station sites on Greenland and Iceland

It is all basic synoptic meteorological data.

104 stations for Arctic and 136 for Antarctic. Data from 1913 to 2002 but there are lots of gaps.

Creating an observational data set. The state of the data set is extracted and stored in ASCII format. Working on a guide doc and working on getting as much data into it as possible.

Money has come though Chris Shuman at NASA via INSTAAR.

Currently not in a format that anyone can use. Hoping to extract it out into a more useful version that other people can use.


Melt-Onset Dataset• The melt onset project has been raising a number of concerns

Problem: We cannot intercalibrate the melt-onset product in an understandable and predictable manner.

When the calibration coefficients used to adjust the Tbs, so that there is consistency between SMMR-F8-F11-F13-produce inconsistent results

o We've found that the F11/F13 adjustments cause larger differences during the overlap period than not using them. (Mark Anderson however feels that we shouldn't just not apply the adjustments, since we don't know how it affects the F8/F11 consistency.)

o We could look at the POLES air temperature during the 1995 F11/F13 overlap period and see which method matches better with the POLES data. This might shed some light on whether or not to apply adjustments to F11 or F13 Tbs. (We are doing some work in this area now.)

o What we really should be doing is looking at the POLES data for the whole time-series to access how accurate the melt onset product really is. This is then becoming more of a research project.

o We really do want to update the time-series (it now only goes through 1998) but in us trying to do that, all these other issues have surfaced. So do we just continue what was previously done, or do we try to make a more accurate product?

Questions to PoDAGo Suggestions on how to proceed?o How much resource to put into this product?o Continue with previous intercalibraiton methods, and document and caution users about

the variabilityo Don’t do anything, leave product as ending in 1988?o Research methods and/or find a research partner to update?


Sea Ice Motion Data Set(s)• Sea Ice Motion Data Set SSMI, Blended, Buoy, AVHRR.

• Has not been updated by providers (Fowler/Maslanik), they are not planning more updates. Do we want to take over the updating?

• All done with Shell scripts or IDL routines.

• Has a significant number of users.

• Would require some resources to transfer code to NSIDC and run updates. (maybe a month of Fowler staff time)

• Question to PoDAG: Should NSIDC take on updates to this data set

now (and on-going)


HARA Data Set UpdateMark Serreze says:… In my opinion, we really need to consider whether this is a worthwhile expenditure of time and resources. The reason is that the NOAA "CARDS" effort has put together a global data set of all rawinsonde data which for many stations is updated through 2000. I've looked at the station inventories and all the Arctic stations are there. The CARDS home page is:

http://www.ncdc.noaa.gov/oa/climate/cards/cards_homepage.html

… So, while it may sound like I'm passing the buck, NOAA seems to have the Arctic rawinsonde problem well in hand. My feeling is that HARA, while an excellent idea at the time, is obsolete.

Questions to PoDAG• Do we not update HARA, and instead build an interface to the CARDS data stream?


PARCA• NSIDC has basic metadata for and advertises 15 data sets,

served by PIs. • Nine potential other data sets were listed in January 2000

PARCA status report.• Jump page seems to be working and we have heard no

complaints from users.• May be renewed interest in these data when ICESat data

becomes available.• What happens to these data in five to ten years?• If NSIDC is to archive these data, we should start now. It will be

more difficult to fund in the future.• Questions to PoDAG:

Should we or NASA pursue the potentially missing data Should we start to archive the data? (Cost: 2-4 weeks per data set)

Our DAAC Quarterly Response to Maryanne Esfandiari (MAE) request

Top 3 Issues Forced addition of functionality to ECS that we may not need, but requires

support. New functions are delivered without rigorous test and validation.o ECHO (BMGT, verification of our metadata in ECHO)

Growth at NSIDC is challenging the current organizational structure. We are searching for an organizational model that fits size and still provides flexibility to take on new projects and copes with the as yet unclear SEEDS data management model.

EOS satellites have brought increased number of products and volumes of data to bear on cryospheric science issues. However, the community is requesting long-term climate data records. If NSIDC DAAC is to continue participation in development of climate data records, issues of how we become involved in EOS follow-on missions (e.g. NPP/NPOESS) and the how and where long term archival of current data need to be resolved

31

Issues from the DAAC

• EMD Contract Management Coordination We would like input into the management process Alliance EMD Working Group a step in right

direction (We do have excellent local support and

cooperation)• EMD Contract Staffing at NSIDC

NSIDC is unique from the other 3 ECS DAACSo Smaller staff – requires cross trainingo Prior decisions on skills split limit options nowo Want flexibility to staff EMD and DAAC with optimal skills

mix and to determine this locally

32


• Local ECS Control, allowing modification of ECS, linkage of new functions maintain local baseline. Requesting better documentation of ECS software,

APIs etc., ability to swap modules into ECS Benefits:

o Insertion of new modules specific to our needs o Improve cost containmento Facilitate insertion of non-EOS data into ECS

Shrink ECS core code baseline

33


• ICESat Longevity and cyrospheric altimetry data management ICESat has a shortened lifetime LTA sooner than originally planned Community will still require support and access to

ICESat data, how will NSIDC provide it without mission?

• SEEDS model only works if there’s infrastructure in place…the CLPx experience CLP Experiment program manager came to NSIDC

for DM services because of our reputation. NSIDC could only accept work at the funding level

offered because infrastructure was already in place.

34


• LTA still unclear

• Security and Privileged Access Issues See next viewgraphs

35

Challenges

• How do we stay focused on science community wishes? Maintaining continuity of observations over the coming

10-15 years How do we develop and/or maintain climate data

records?

• How does NSIDC maintain the staff skills needed to be responsive and flexible? While operating a complex ECS In the face of ESDIS cost reductions

o We are small, 1 or 2 staff reductions mean loss of skill areas Need to identify reward structure for improving

efficiency
