GOES-10 Science Test - Dry Run Results of March 12, 1998


compiled by Dan Baumgardt - Science and Operations Officer NWSO La Crosse

On March 12, 1998, NWSO La Crosse participated in the GOES-10 science testing dry run. The NWSO La Crosse used the RAMSDIS workstation as an ingestion platform with a 64k bps (burst 128K bps) frame relay network connection. We are not a NOAAPORT ingest site.

- The test was conducted from 1500-1930 UTC.

- Findings:

  1. Based on the dry run, GOES-10 data ingest for the 1-month science test will not provide quality satellite data for operations on the RAMSDIS workstation at full ingest strength. Too high a percentage of images were either missing or partially received. However, 1/2 of the dry run dataset may provide scientifically useful imagery and full image receipts.
  2. NCEP model grib data ingest was NOT adversely affected.
  3. Normal GOES-8 FRN data ingest from the CRH satellite imagery server continued through the GOES-10 test without adverse effects. Thus, we had dual satellite imagery datasets for comparison on GARP and RAMSDIS. Again, no adverse effects.
  4. Initial conversion to the GOES-10 test had a few problems. Hiro Gosden from CIRA gave excellent support to help work through the RAMSDIS ingest problems and allow the test to be conducted nearly as scheduled.
  5. NWSO La Crosse received 1km visible imagery t+7-10 minutes after image time (t).
  6. NWSO La Crosse will particiate in the spring GOES-10 testing at 1/2 the full data ingest level.
About the Dry Run and Other Findings

- GOES-10 data ingest was set up for the maximum to test the impact to other office datasets being regularily downloaded. This schedule was:

RAMSDIS GOES-10 Products & Schedule

Daytime:

1 km visible (24 frames) - 12 images per hour (12/hr) (2 hr loop)
4 km visible (16 frames) - 2/hr (8 hr loop)
4 km IR 2 (16 frames) - 2/hr (8 hr loop)
4 km IR 4 (16 frames) - 2/hr (8 hr loop)
16 km PS IR 3 composite (24 frames) - 1/hr (24 hr loop)
4 km Reflectivity product (16 frames) - 2/hr (8 hr loop)

** The remaining products, or the products not mentioned, will be suspended
throughout this test:

12 km PS IR 4 (F6)
8 km IR 3 (F9)
1 km Vis & IR 4 radar projection (F3 & F4)
4 km Vis & IR 4 running mean (Alt-F1 & Alt-F5)
Floater loop (Alt-F8)


- The GOES-10 data received at NWSO La Crosse and displayed on the RAMDIS workstation is given below. According to Hiro Gosden of CIRA, the main symptom with saturating the bandwidth of the FRN connection is partial or missing images. This can also be a problem with the RAMSDIS server back in Washington.

- The graphic below demonstrates the FRN traffic in and out of the office during the test (between the red "X"'s). It is interesting to note that the test did not invoke saturation of the FRN during the entire period. The area of high activity from 19-21 and 07-09 UTC daily (filled green areas) represents the downloading of the Meso-Eta NCEP model data. This was not during the GOES-10 test time.

In comparison to the day prior (between the "Y"s), it seems the GOES-10 data did cause more time where the FRN line was saturated.

- Below is a detailed listing of the NCEP model data ingest for the test period. Regarding NCEP model data, NO delays were noted during the test time. Due to NCEP model production time differences, a comparison of NCEP grib data receipt on test day versus previous days would not be a true representation for the GOES-10 data impact.
