Monitoring ecosystems at regional or continental scales is paramount for biodiversity conservation, climate change mitigation, and sustainable land management. Effective monitoring requires satellite imagery with both high spatial resolution and high temporal resolution. However, there is currently no single, freely available data source that fulfills these needs. A seamless fusion of data from the Sentinel-3 and Sentinel-2 optical sensors could meet these monitoring requirements as Sentinel-2 observes at the required spatial resolution (10 m) while Sentinel-3 observes at the required temporal resolution (daily). We introduce the Efficient Fusion Algorithm across Spatio-Temporal scales (EFAST), which interpolates Sentinel-2 data into smooth time series (both spatially and temporally). This interpolation is informed by Sentinel-3’s temporal profile such that the phenological changes occurring between two Sentinel-2 acquisitions at a 10 m resolution are assumed to mirror those observed at Sentinel-3’s resolution. The EFAST consists of a weighted sum of Sentinel-2 images (weighted by a distance-to-clouds score) coupled with a phenological correction derived from Sentinel-3. We validate the capacity of our method to reconstruct the phenological profile at a 10 m resolution over one rangeland area and one irrigated cropland area. The EFAST outperforms classical interpolation techniques over both rangeland (−72% in the mean absolute error, MAE) and agricultural areas (−43% MAE); it presents a performance comparable to the Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM) (+5% MAE in both test areas) while being 140 times faster. The computational efficiency of our approach and its temporal smoothing enable the creation of seamless and high-resolution phenology products on a regional to continental scale.

OREGON VOICES The Romance of John Reed and Louise Bryant New Documents Clarify How They Met by Michael Munk LOUISEBRYANTANDjOHN''jACK" Reed's romance? ifnot theirfidelity ? endured beyond their initial 1915 meeting in Portland, Oregon, to the end of their lives, when they each expressed loving thoughts for each other. Shortly before her death, in a hurriedly penciled postcard from Paris to radical artist Art Young, Bryant declared, "If I get [to heaven] before you do or later ? tell JackReed I love him." Shortly before typhuskilled him at age thirty-three inMoscow, Reed expressed similar thoughts in a poem hewrote fromprison. The poem, titled "A Letter to Louise," closes: Letmy longing lightlyrest On her flower petal breast Till the red dawn setme free To be with my sweet Ever and forever...' When JackReed and Louise Bryant took up with each other in Portland more than ninety years ago, their love affairquickly became one of themost notorious romances to have been born in Oregon. As their celebrity grew, world-wide curiosity inspired efforts to describe themeeting of a famous radical writer and a Portland journalist, ameeting that launched the couple on a romantic political journey that ended inMoscow in thewake of theBolshevik revolution. Although we may never know the precise circum stance of theirfirstaccidental meeting, it most likelyhappened inPortland on December 15,1915,a fewhours before they expected to be introduced by mutual friends Carl and Helen Wal ters at dinner in their Labbe Building studio.2 Scholarly biographies and popular-press accounts, including two Soviet films, an opera, and a play pro duced in the Soviet Union, have tried to depict the Reed-Bryant romance, but if Americans are aware of ittoday, it isprobably because they are among themillions who saw Reds ? the 1981 Oscar-winning Hollywood film that ? 2oo8Oregon Historical Society Munk, The Romance of JohnReed and Louise Bryant 461 /o/z?iteedfl?? Louise Bryantpose at theirhome inCroton-on-Hudson, New York, in about 1917. dramatized Bryant and Reed's lives and times.3 Warren Beatty and Diane Keaton play the couple in the film, which opens in "Portland, 1915." Its first ten minutes depict their initial few days together,and Beatty,who was also the film'sdirector, devotes the restofReds' threehours to thecouple's subsequent five years of Bohemian romance and literaryand political activism inNew York, Croton-on-Hudson, Cape Cod, 462 OHQ vol. 109, no. 3 and France. It ends tearfully, with Bryant attending Reed's death in a Moscow hospital room while Soviet revolutionaries struggle to succeed outside. Neither Reed nor Bryant docu mented how they met, and their biographers have provided so many different versions that the event has acquired a mythological aura. Although they actually met about a year and a half later,Reds places the couple's firstmeeting after Reed's radical rant on class war that shocked theUniversity Club (named "Liberal Club" in thefilm) during the summer of 1914. Beatty has Bryant accosting Reed as he was leaving the club and gaining his attention by aggressively declaring her radical literary creden tials.The film'shistory advisor, Robert Rosenstone, remains among themost authoritative of Reed's biographers, and he likelyhad to sign offon Beatty's artistic license for that scene.4 The earliest of Reed's serious biographers, Granville Hicks, relied on Bryant's friend Helen Walters and accurately dated the meeting during Reed's 1915Christmas visit to his mother in Portland. Hicks also correctly describes Bryant, who was attracted byReed's radical reputation and was a booster of his articles inThe Masses and the Metropolitan, as hav inghoped for some time tomeet him.5 Biographies of the couple offer other alternatives. Citing an informant, one tells readers theymet at Bryant's friend Clara Wold's home.6 Citing another, Mary Dearborn says they were "formally introduced" in 1914 at the home of Eva and Norma Graves (now theRimsky-Korsakaffee House at 707 SE Twelfth Avenue).7 Some are less precise. The earliest writer about their love storymakes it at "one of the artists' meeting places."8 Alfred Powers points to a party where Reed spoke, while Harold Hughes refines that to a "Portland cocktail party."9 Sarah Bard Field claims "I brought...

A Mute Rid Harmon Aipst 1,1952-May 20,2KM Rick Harmon (left),Michael Munk, and Omar "Slug" Palmer (back to camera) at theOregon Historical Society's annual meeting in 1997, where Munk received the Joel Palmer Award. RickHarmon, editor of theOregon Historical Quarterly from 1987 to 1999,died on May 20,2004. We are grateful toSteveHallberg for allowing us toreprint part of theeulogy hewroteforRick and toRick's other colleagues for helping us remember hismany contributions to thejournal and theOregon Historical Society. I met Rick for the first time in 1983when he arrived at theOregon Historical Society to takeon theposition of oral historian. Naturally, his hiring raised a few eyebrows among us northwesterners, who were not quite surewhether we could safely entrustOregon history to a California!!. It took no time at all, however, to figure out thatRick was exactly the right person for the job. His intellect,work ethic, and integrity were evident right from the beginning, and theymade a strong impression on me and his other colleagues. Rick stepped into an oral history program with a strong foundation laid down by his two predecessors, Charles Digregorio and Linda Brody Dodds. His biggest innovation was amove toward longer,more in-depth interviews that explored all stages of a person's life;and over the next fewyears, Rick used this approach to conduct remarkable sessions with people as diverse as federal judge Gus Solomon, civil rights activist Kathryn Hall Bogle, and writer Clyde Rice. Excerpts from several of his oral histories, published in theOregon Historical 502 OHQ vol. 105, no. 3 ? 2004 Oregon Historical Society Quarterly, convey just how good an interviewer he was ? able to draw people out and get them to think and speak about their lives in revealingways. In 1986,Rick was chosen to succeed Priscilla Knuth as editor of theOregon Historical Quarterly, a post she had held for three decades. "PK" would have been a tough act for anyone to follow, and in some respects, the two of them could not have been more different. What they shared was a commitment to thework. Over the year thatRick spent working alongside Priscilla, the two formed a strong bond, and PK passed on stewardship of theQuarterly in 1987, confident that it was in good hands. When I think of Rick as editor, I picture him seated inhis office, shoes off, cross-legged with his feet tucked underneath him, his chair pushed farback fromhis desk, leaning across empty space with his red pen to edit copy at arm's length. I never figured out how he could work in that position, much less get in and out of it. Itmust have suited him, though, because he was remarkably productive. A quick browse through theQuarterly's table of contents for the years of his tenure reveals an astounding range of subjectmatter, from oil drill ing inHarney County to an episode ofMcCarthyism atReed College. In 1993, Rick added "The Journal ofRecord forOregon History" to the titlepage of the Quarterly. He set thebar high and lived up to the standard. In 1991,Rick added a feature that I used to look forward to almost asmuch as the articles themselves: the editor's introduction. It was typically a shortpiece intended to set the stage for the articles, but the thinkingwas original and the writing was pithy. It was thefirst indication some ofus had thatRick was as good awriter as he was an editor. I think the experience of producing the editor's in troductionwhetted his appetite to spendmore time on his own writing. Between 1995 and 1998,while attending to themillion and one details involved inputting out a quarterly journal, Rick published two fine articles of his own inOHQ, one on the history of the Bull Run Watershed and another on Oregon geologist Thomas Condon. Eventually, the desire tomake writing a full-time occupation won out, and in 1999Rick resigned his position as editor. By a fortunate circumstance, a project ideally suited to Rick's talents and interestscame along a short time later when theFriends ofCrater Lake National Park asked him towrite the park's centennial history.He had been waiting for just thiskind of opportunity?the chance todeal with complex environmental policy issues...
