NPP Status Update

Before I wrote about the mission launch on Oct. 28th, soon after the satellite reached it's final orbit.  After review, the satellite passed it initial stages and soon it's instruments were operational.

Earlier Nasa reported that the NPP Satellite had captured it's first hi resolution image on Nov. 21st.
This image was taken by one of the five instruments on board.

The one instrument called VIIRS, (Visible Infrared Imaging Radiometer Suite), which can detect fog at night just by reflected moonlight.  There is word that this may be able to further enhance early warning for fog alerts.  The imaging system will measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion, fires and Earth's albedo.  Albedo is the fraction of sunlight reflected by the moon, or also known as moonlight. The NPP satellite is a big step from the satellites used back in the early eighties.

The Schuylkill River at Norristown PA

The National Weather Service issued a Flood Warning last night and indicated that the  Schuylkill River reached flood stage as of 5:30 AM this morning. 

This chart shows that at 10:30 AM, the river reached one foot over flood stage and at 11 AM it had started to rain again as I write this.  At this point it is considered minor flooding, still please use caution when driving today.

Attached here is the link with the Flood Stage chart and a Map.
