Reprocessing Earlier this year, the SIPS began the most comprehensive reprocessing effort to date. The ESDT Version 3 data set will feature the following enhancements: – L2A products generated with Wentz Version 7 algorithm – Inclusion of ISO-compliant lineage information and digital object identifiers (DOIs) in data files – Updated browse imagery AMSR-E Joint Science Team Meeting Oxnard, CA Sept. 4-5, 2013 6
7
Wentz Version 7 algorithm The new brightness temperature products generated at SIPS-RSS – use AMSR-E L1A V03 dataset as source input – use the new RSS Version 7 radiative transfer model algorithm, intercalibrated with other microwave radiometers, such as SSM/I F13 and WindSat, thus bringing all satellite microwave radiometers to a common calibration standard – show improved calibration over land, based on heavily vegetated tropical rainforest scenes – improve Radio Frequency Interference (RFI) Flagging in response to new geostationary sources. AMSR-E Joint Science Team Meeting Oxnard, CA Sept. 4-5, 2013 7

Provenance Capture All AMSR-E ESDT Version 3 products will include new metadata routines that contain or capture dataset DOIs and ISO Lineage. – The digital object identifier (DOI) uniquely identifies a dataset. Metadata about the data is correlated with the DOI. The DOI for an object is permanent, whereas its location and other metadata may change. – Storing ISO-compliant lineage information in data files means that processing history stays with the files. AMSR-E Joint Science Team Meeting Oxnard, CA Sept. 4-5, 2013 8
9
Enhanced Browse Imagery All AMSR-E ESDT Version 3 products will benefit from a new browse image process which includes – new 24-bit PNG images with embedded metadata, such as source science data file name, parameters, date/time stamp, projection, etc. – KMZ files suitable for display on map or globe – the traditional “framed” image with title, color bar and annotations Full resolution browse imagery, data only, will be provided as map layers to NASA’s Global Image Browse Service (GIBS) – Selected channels or variables from each product, suitable for overlay on MODIS background images AMSR-E Joint Science Team Meeting Oxnard, CA Sept. 4-5, 2013 9
10
Reprocessing Plan L2A reprocessing (addition of metadata and browse image generation for RSS-produced L2A data) completed at SIPS-GHRC in July. L2B and L3 datasets will be reprocessed individually throughout 2014-15 as algorithm updates are received from TL-SCF. Assuming a final L2A dataset update by SIPS-RSS in late 2015, SIPS-GHRC will perform a full mission reprocessing of all products in 2016 using final L2A as input with latest available science algorithm.

Introduction The AMSR-E SIPS is currently negotiating with NASA HQ to do standard and near real-time product generation – SIPS in Huntsville, AL will generate climate research quality products from JAXA Level-1R data, using algorithms adapted from AMSR-E processing by the US Science Team. These products will be archived at the NSIDC DAAC. – SIPS will also generate LANCE (Land Atmosphere Near real-time Capability for EOS) products for users who are interested in monitoring natural and man-made hazards in near real time (no archive).

AMSR2 Near-Real-Time Processing NASA’s LANCE system is eager for AMSR2 products. AMSR-E was second only to MODIS with LANCE users: – “Our flood detection system depends on AMSR-E data, and is used by governments in many countries (e.g., http://www.gdacs.org/flooddetection/ ).” http://www.gdacs.org/flooddetection/ Tom De Groeve, Joint Research Centre of the European Commission – “At the Cooperative Institute for Meteorological Satellite Studies at the University of Wisconsin, we make continuous use of the AMSR-E retrievals of total precipitable water shared in real-time on the LANCE servers... Microwave-frequency retrievals of low-level water vapor are usually the earliest indicator available for tropical cyclone development in remote ocean environments.” Chris Velden, Cooperative Institute for Meteorological Satellite Studies at the University of Wisconsin AMSR-E Joint Science Team Meeting Oxnard, CA Sept. 4-5, 2013 16

Discussion SIPS plans to use JAXA L1R as input to the US Level-2B and Level-3 algorithms – Already signed GCOM-W1 AMSR2 User Agreement and registered with JAXA GCOM-W1 data system. – What other operations agreements do we need to prepare and with whom do we coordinate? – What arrangements do we need to make for routine, automated data delivery and with whom do we coordinate? – Can we receive L1R per ½ orbit in near real (similar to L1B delivery to GSFC PPS)? LANCE data latency requirement is within 3 hours of observation, but sooner is better… – What else do we need to consider as we plan to receive Level- 1R data directly from JAXA?
