HyspIRI Airborne Campaign

Activities relating to the HyspIRI airborne campaign

In 2013 and 2014 NASA will conduct airborne campaigns for the HyspIRI mission.  For these campaigns, NASA will fly the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) and the MODIS/ASTER Airborne Simulator (MASTER) instruments on a NASA ER-2 aircraft  to collect precursor datasets in advance of the Hyperspectral Infrared Imager (HyspIRI) mission. The primary goal of this activity is to demonstrate important science and applications research that is uniquely enabled by HyspIRI like data, taking advantage of the contiguous spectroscopic measurements of the AVIRIS, the full suite of MASTER TIR bands, or combinations of measurements from both instruments.

NASA solicited proposals for investigators to participate in these campaigns. NASA received 49 proposal and selected 14.
Data will be acquired over large blocks of California as part of these campaigns shown in the figure below.

A JPG of the flights and WRS2 is available from <here>

The goal is to acquire cloud-free data over all blocks 4 times in 2013. The periods during which these flights will occur are as follows:

April 1 – April 23, 2013
May 22 – June 11, 2013
September 9 – 20, 2013
October 7 – 18, 2013

These periods are intended to provide approximately seasonal coverage.

Frequently asked questions:

1. What time of day will the data be acquired? Typically between 10 am and 4 pm but this will depend on the season since we want to maximize the signal to noise.

2. Have the locations of these lines been finalized? Almost, the science team is currently finalizing the lines, typically extending a few of the lines to make sure key locations are covered.

3. Can anyone get the data? Yes, Level 1 (radiance at sensor) and Level 2 (reflectance, temperature, emissivity)  data will be made freely available over the web.

4. Where do I get the data? The data will be available through the AVIRIS and MASTER websites.

5. Will there be any night flights? Yes a small number of hours are reserved for night flights.

6. Will there be any flights over fires (prescribed or natural)? Yes a small number of hours are reserved to acquire data over fires.

7. What pixel sizes will the data have? AVIRIS will have 20 m pixels and MASTER will have 50 m pixels.

8. What swath widths will the data have? AVIRIS will have an 11 km swath and MASTER will have a 35 km swath.

9. What plane will the instruments be mounted on? Both instruments will be on the ER2 which will acquire data from 20 km.

10. Which investigators were selected from the ROSES call? <click here>

11. Which order will the boxes (regions) be flown. The order will depend on the weather but the default order is:
1) Southern California; 2) Santa Barbara ;3) San Francisco Bay; 4) Yosemite ; 5) Lake Tahoe

12. How can I find out the current weather for planning purposes? Try these sites:

Current Forecast - US

Geostationary satellite images - US

Model and Analysis Data for Current Forecast

13. Can I find out where the ER-2 is when the sites are being flown?

Yes, use the aircraft tracker
