EU10/01, 168/2010, Loobos

[jb362]

Data location: ~arsf/arsf_data/2010/flight_data/western_europe/EU10_01-2010_168_loobos

Data arrived from ARSF via network transfer on 23/06/2010

Scientific objective:

1.Key impact factors on CO2 and H2O fluxes
1.1 examine the influence of within-site elevation changes using flux tower observations, airborne LiDAR data, and ecosystem models data (Loobos)
1.2 develop an approach to allocate CO2 and H2O fluxes to specific tree species of a mixed forest (Norunda)
1.3 assess the influence of forest thinning on CO2 uptake (Norunda)
1.4 evaluate above findings and test transferability of findings (Tharandt)
1.5 investigate the impact of storm damage (Tharandt)

2. Reducing uncertainty in the upscaling of greenhouse gases

2.1. develop an approach to evaluate airborne flux measurements using flux tower data, footprint model and airborne LiDAR data (Loobos)
2.2 use airborne LiDAR data to validate GLAS/ICESat for different forest biomes, where accurate tree height and vegetation cover density will be co-located with GLAS footprints
2.3 evaluate the ability of GLAS spatial sampling density to represent the wider field site
2.4 develop an approach to model CO2 and H2O fluxes on a regional scale using GLAS/ICESat data and generate key driving parameters for land-surface models
2.5 evaluate whether regional CO2/H2O flux models driven by satellite optical data can be improved by the addition of tree height information from satellite LiDAR

Priority: a5

PI: N. Kljun

Sensors:

• Eagle (01/09/2010)
• Hawk
• Leica LIDAR (06/09/10)
• RCD (26/08/10)

This directory needs to be backed up in the repository

[jb362]

IPAS navigation for this project has been processed.

[benj]

RINEX data downloaded from Thelma.

[ella]

Applanix navigation processing now done. Files located in ARSF workspace.

[jb362]

Started hyperspectral processing

[jb362]

I need to check the Sbet file times against the flight line times in PosGNSS for this project as they don't seem to match the logsheet, however the extract directory on workspace is empty so there is no saved PosPac/PosGNSS data and no raw files. I think Loobos is going to have to be re-downloaded so that I can put the raw files back into workspace and then open up the project in PosGNSS

[jb362]

downloading raw files done

[jb362]

The -1.nav didn't contain the navigation data but we have used the datacube.nav file and renamed it as -1.nav. Original -1.nav file renamed as -1.nav_old.

[jb362]

.raw file missing for first eagle line

[jb362]

No eagle data for flight line 1 or 9 and no hawk data for flight line 9 because of missing .raw files

[jb362]

Actually .raw files do exits for flight line 9 on each sensor... I don't know why neither produced .tif files

Results:

1. PI name spelling in Readme front page --> should be N. Kljun

2. Flight line 9 for eagle and hawk has raw files and lev1's, so should produce .tif's as well.

3. Since line 1 for eagle does not have a raw file, the rest of the lines will have to shift up so there is a continuous set of lines 1-28 for eagle. For the readme, this means that the lev1's and tif's 1-28 will need to be matched with the recorded line numbers in the logsheet for lines 2-29 (1 will be 004, 2 will be 019 etc.). This therefore applies to lev1's, lev3's and readme which will need to be renamed. (all this assuming eagle line 1 can not have a lev1 and lev3)

4. Remove any hidden files in the delivery, currently there is just .Read_Me-20100722.tex.swp in EU10-01.

5. Remove the .tex after the pdf is produced. Also remove the .tex in the screenshots directory.

6. Missing bin directory, with instructions on downloading azgcorr (see ​http://arsf-dan.nerc.ac.uk/trac/wiki/Processing/FilenameConventions#Delivereddata)

The large SCT offset for flight line 15 is due to a sync error.

The header file for eagle flight line 16 had to be corrected so that "lines = 9596", rather than "lines = 1837" as in the original header file.

[jb362]

Sorry, these offsets are for Santander (!!!)

Delivery checking camera.

[jb362]

Everything looks fine. Should PI on Readme just be N. Kljun or Dr N. Kljun?

[benj]

Doesn't really matter. Pick one.

[emca]

Photography data has been sent to PI 26/08/2010 along with LiDAR and Eagle data from day 168 (ticket ​#345)

[knpa]

Finished processing LIDAR, creating delivery.

[jb362]

Eagle data delivered 01/09/2010.

[ella]

Starting LiDAR delivery check.

[ella]

LiDAR check complete.

-Flight logsheet misspells site name.

-Read_me document figure 1 is intensity image without vectors but the caption says it has vectors overlaid.

[knpa]

Fixed above issues, preparing delivery to PI.

[knpa]

LIDAR delivered today (06/09/10) to N. Kljun at Swansea University.

[knpa]

Has been transferred to repository and can be r-synced.
