On Sunday 2 August, CARVE flew a 7 hour science flight over Dillingham, Alaska.

CARVE observed enhanced CH4 in the Dillingham area.

CARVE flew 23 flight hours, collecting science data from the North Slope, Seward peninsula and Dillingham / King Salmon, Alaska.

On July 11, CARVE flew Over Dillingham / King Salmon and collected the following data (this was CARVE's first time collecting data over this area).

The above plots show reduced CO2 and enhanced CH4 signals.

This week, CARVE flew a short flight to Lake Minchumina and two flights to the North Slope. (Barrow and Prudhoe Bay)

On the Fourth of July, CARVE flew up to Barrow and Prudhoe Bay. CARVE acquired enhanced CH4 South of Barrow and South of Prudhoe Bay.

CARVE's IR surface camera indicated spring like temperatures on the North Slope. 

On Monday June 15, CARVE flew its last flight for the June campaign, flying over the North Slope and acquired enhanced CH4 South of Prudhoe Bay.

Also this week, Thomas Kurosu, presented three years of CARVE FTS observations at the 11th International Workshop on Greenhouse Gas Measurements.

CARVE continued flight operation in Alaska last week.  CARVE flew over Fort Yukon, Nikolai and Innoko (see track plot below) for a total of 14 flight hours.

The Innoko flight on Sunday, June 14 shows enhanced CH4 and CO2 in the Innoko science area.

On June 2 – 4, CARVE flew to Innoko, Seward Peninsula and Bethel.  The flight over the Seward Peninsula on June 3 showed enhanced CH4.  

CARVE also flew on June 7 to Barrow.

With continued good weather, flew an additional 11.7 flight hours in 3 days. 

CARVE flew science flights over Fort Yukon, Nikolai and Ruby.

During the October campaign, the CARVE team successfully executed 6 flights and accumulated nearly 40 flight hours. Flights to western Alaska in particular showed that there were still strong surface-atmosphere emissions of CO2 and CH4 despite freezing surface conditions.

Also this week, CARVE's team received correspondence from the Proceeding of the National Academy of Science (PNAS), which has given final approval for publication of "Methane emissions from Alaska in 2012 from CARVE airborne observations"

On 24 and 25 March, CARVE flew two test flights both in the San Joaquin Valley (SJV). Both test flights were successful and CARVE is ready to depart for Fairbanks, Alaska. Data below shows enhanced CO2 and CH4 while flying low level (500 feet above ground level) over the southern SJV area.

Due to continued inclement weather this week in Alaska, CARVE was only able to fly two additional days.  14 April to North Slope, and 15 April to Upper Kuskokwim Valley.
