## ECS Release 5A Focus

## ASTER Scenario

***ASTER Goals***
***- ******Java****** ******DAR Tool Usage***
***- Backward Chaining Workaround***
***- SCF QA Metadata Update Workaround***
***- Simplified ASTER Expedited Data Support***
***- Data Tape Ingest***
***ASTER Preconditions***
***ASTER ESDTs Inserted into ECS***
*** ******-AST_ANC, AST_EXP, AST_L1A, AST_L1BT,***
*** ******AST_09T, AST_04, AST_05, GDAS0ZFH***
***ASTER PGEs passed SSI&T and installed***
*** ******- ACT, ETS, BTS***
***Ancillary data inserted into Data Server***

## ASTER Scenario:  DAR Support

**PRODUCTION**

**External**
**Data Provider**

**User**

**DAR Submission**
**Data Subscription**
**Data Insertion**
**Data Notification**

## DAR Support

- Deliver

**ASTER Scientist decides**
**to request ASTER data**
**requiring a Data Acquisition**
**Request**

- Store

**DAR Support**

## ASTER: Client Request Process

**ASTER: Client Request Process**

**ASTER Scientist determines an area of interest.  The scientist**
**decides to request an ASTER data take over that area, using the**
**Java DAR Tool.**

## ASTER:  CSCI/Component Rolein Client Request

**ASTER:  CSCI/Component Role****in Client Request**

## DAR Support (Cont.)

- Deliver

**ECS submits DAR to ASTER Ground**
**Data System (GDS) in Japan**
**receiving a DARid in return**

- Store

**DAR Support (Cont.)**

**GDS**

## ASTER: Request Data Take Process

**ASTER: Request Data Take Process**

**ECS-GDS Gateway submits a request for a data take over the area**
**of interest.  GDS responds with a DARid.**

**GDS**

## ASTER:  CSCI/Component Rolein Data Take Request

**ASTER:  CSCI/Component Role****in Data Take Request**

## DAR Support (Cont.)

- Deliver

**Subscription is submitted on**
**behalf of user for notification**
**on receipt of AST_L1BT (TIR)**
**data**

- Store

**DAR Support (Cont.)**

## ASTER: Submit Subscription Process

**ASTER: Submit Subscription Process**

**MoJo Gateway submits subscription for notification on the occurrence of**
**AST_L1BT:Insert event, qualified with the DARid.**

**2. Subscribe (L1BT:Insert, e-mail**
**    ****notification)**

## ASTER:  CSCI/Component Rolein Subscription Submission

**ASTER:  CSCI/Component Role****in Subscription Submission**

## DAR Support (Cont.)

**After receiving D3 tape from**
**GDS, operator mounts tape**
**and begins ingestion of data**

**DAR Support (Cont.)**

## ASTER:  D3 Tape Ingest Process

**Some time later, after receiving D3 tape in a shipment,**
**DAAC Operator mounts tape and begins ingest activities.**
**Tape contains AST_L1BT (L1B TIR) data.**

## ASTER:  CSCI/Component Rolein Ingest D3 Tape Operations

**ASTER:  CSCI/Component Role****in Ingest D3 Tape Operations**

## DAR Support (Cont.)

**Ingested AST_L1BT**
**data are archived**

**DAR Support (Cont.)**

## ASTER:  Ingest Archive Insertion Process

**Archive AST_L1BT (L1B TIR) data granules.**

## ASTER:  CSCI/Component Rolein Ingest Archive Insertion

**ASTER:  CSCI/Component Role****in Ingest Archive Insertion**

## DAR Support (Cont.)

**Update catalogue with reference**
**to new L1BT data**

**DAR Support (Cont.)**

## ASTER:  Inventory (Metadata) Update Process

**Add metadata for AST_L1BT (L1B TIR) data granules**
**to the Sybase/SQS database.**

## ASTER:  CSCI/Component Rolein Inventory (Metadata) Update

**ASTER:  CSCI/Component Role****in Inventory (Metadata) Update**

## DAR Support (Cont.)

**Insert terminates with an insert event**
**notification to Subscribe. Subscribe**
**e-mails ASTER Scientist notice of**
**a completed AST_L1BT granule**
**    ****insert**

**DAR Support (Cont.)**

## ASTER:  Event Notification Process

**Notify all AST_L1BT:Insert event subscribers whose**
**DARid numbers are matched with the ingested granules.**

## ASTER:  CSCI/Component Rolein Event Notification

**ASTER:  CSCI/Component Role****in Event Notification**
